Further reducing the error
Laetitia Laub was born and raised near Lausanne. She studied mathematics and physics at the Federal Institute of Technology in Lausanne (EPFL). Since August 2017, the 24-year-old junior scientist is writing her doctoral thesis in theoretical physics at the University of Bern. In her thesis she deals with the anomalous magnetic dipole moment of the muon and the reaction of this particle in the magnetic field. "Many people are currently working on this theoretical problem with the aim of further reducing the calculation error of the dipol moment. This is also because a better experimental value for the dipole moment will be probably found at Fermilab in the US and J-Parc experiment in Japan soon, " says Laetitia Laub.

Measuring the Invisible Cosmos
In 2021, the European research satellite Euclid will be launched into space. With Euclid, scientists from Switzerland and 15 other countries want to gain a better understanding of dark matter and dark energy. These two 'things' fill large parts of the universe in the view of modern astronomy, but neither dark matter nor dark energy have been directly observed so far. Researchers at the University of Zurich have prepared a complex computer simulation of dark matter in preparation for the Euclid mission. This mission is of great interest not only to astronomers and astrophysicists but also to particle physicists since particle physics is on the quest for the discovery of the nature and structure of dark matter with its own experiments.
The best way to new physics
If you are looking for unknown things, you usually do not know which way to go to find the unknown. This dilemma is also faced by scientists who want to advance into previously unknown areas of elementary particle physics. And yet they have to find a consensus on which experiments promise the greatest gain in knowledge in the next years and decades. For this purpose, the Swiss particle physicists are currently working on a new research roadmap.
Mobile phone sensors, fit for cutting-edge research
The large particle accelerator LHC at CERN in Geneva enables scientists to get precious clues to understand the nature of matter in the next two decades of data taking. The power and performance of this huge research apparatus needs to be constantly improved for this task. A silicon sensor, which the junior researcher Claudia Merlassino is currently testing at the University of Bern, is planned to be used from 2025 in a large LHC experiment: ATLAS.
Drugs from the particle physics research lab
CERN in Geneva is the world's largest facility for the study of fundamental particles. The equipment that usually serves science can sometimes be used for practical purposes too. That's for example the case for the protons emerging from the Proton Synchrotron Booster (PSB): they are used in the large particle accelerator LHC for scientific experiments. The protons can also be used to produce isotopes that are useful in radiation medicine. Such isotopes are produced in the recently opened facility CERN-MEDICIS.
Un tocco di magnetismo
Quest’autunno all’Istituto Paul Scherrer comincerà la costruzione di un nuovo esperimento di fisica delle particelle per determinare il dipolo elettrico del neutrone. Rimpiazzerà il precedente esperimento, che al momento ci ha fornito la misura alla lunga piú precisa degli ultimi anni e la cui analisi dei dati è ancora in corso. Il nuovo esperimento, disegnato in collaborazione tra il dottorando di ETH Michal Rawlik, puó rivelare delle caratteristiche del magnetismo inimmaginabilmente piccole. Un risultato positivo dell’esperimento potrebbe aiutare a spiegare perché c’è tanta piú materia nell’universo rispetto all’antimateria.
An Unimaginably Sharp Image of Antiprotons

During the last few months, intensive maintenance work on the particle accelerator has been done. The physicist community is hoping to gain new insight into the building bricks that make up our world.
Artistic View on Physics
The highly complex research of elementary particle physics is for most people not immediately comprehensible. An artistic approach can help overcome the inaccessibility of this discipline and make particle physics understandable. This is the basic idea of the art @ CMS program, which is celebrating its five-year anniversary this year.
A Voyage to the Boundaries of Physics
As complicated as particle physics may be, experiments such as those conducted at CERN make it clear how researchers in this discipline work. . However, theoretical physicists, whose work is based on mathematical models, have more difficulty explaining their work. A project from ETH Zurich attempts to provide easy-to-understand insight into a current field of research in theoretical physics.
Heart surgery at CERN
During the recent service pause of the CERN Large Hadron Collider (LHC), a key component of the CMS experiment was replaced at the beginning of March: the new pixel detector is even more powerful than its predecessor – raising hopes for new insights in elementary particle physics.
Research as a peace project
The laws of particle physics apply regardless of place and time, but the laws can’t be explored or their applications studied equally well in any location. Particularly in poorer countries, cost-intensive research projects face big challenges. Against this background, there is a ray of hope that the first Synchrotron in the Middle East for the production of high-brilliance X-ray radiation, called SESAME, will be launched during summer 2017. Switzerland has contributed to the success of this project.
Blocked future

"Like the CEO of a multinational company"
The abbreviation CMS stands for one of the currently largest physics experiments worldwide. Günther Dissertori, a particle physicist at the Swiss Federal Institute of Technology (ETH) Zurich, was recently appointed to the three-headed spokesperson-team of the CMS experiment, which is located at the large particle accelerator at CERN in Meyrin near Geneva. The 47-year-old scientist has to cope with a task that can be compared to the management of an international company with 4,000 employees.
Track and trap – the long search for magnetic monopoles
Is there an elementary particle carrying magnetic charge? This fundamental question is being addressed by an experiment currently performed at CERN near Geneva. Recently the MoEDAL research collaboration published its first findings. No discovery has been made so far, but now the experiment will enter in its hot period. Prof. Philippe Mermod and his team at the University of Geneva play a vital role in the search for the hypothesized fundamental magnetic particle.
Precision with a Broad Benefit
Marco Valente is a PhD student, born in Ticino and is currently working at the University of Geneva.

Mohamed Rameez wins the CHIPP Prize 2016
The prize of the Swiss Institute of Particle Physics (CHIPP) 2016 goes to Mohamed Rameez. The 27-year-old neutrino researcher who just has earned his PhD at the University of Geneva has been awarded for his outstanding contributions to the IceCube Collaboration.
The deuteron too poses a mystery
The deuteron — one of the simplest atomic nuclei, consisting of just one proton and one neutron — is considerably smaller than previously thought. This finding was arrived at by an international research group that carried out experiments at the Paul Scherrer Institute, PSI. The new result is consistent with a 2010 study by the same group, in which the researchers measured the proton and found a significantly smaller value than previous research using different experimental methods. The result from 2010 formed the basis for what has been known since then as "the proton radius puzzle". The new measurement of the deuteron’s size has now given rise to an analogous mystery. It is possible that this will lead to an adjustment of the Rydberg constant, a fundamental quantity in physics. Another possible explanation is that a physical force as yet unknown is at work. For their experiments the researchers used laser spectroscopy to measure so-called muonic deuterium: an artificial atom consisting of a deuteron orbited by an exotic elementary particle known as a muon. The experiments took place at PSI because the world’s most powerful muon source, available here, was needed to produce sufficient muonic deuterium. The researchers have published their new study of the deuteron’s size in the renowned journal 'Science'.

L’alba di una «nuova fisica»
Da inizio giugno, dopo due anni di pausa tecnica, il Large Hadron Collider (LHC) – il potente acceleratore di particelle del CERN – è stato riattivato e ha ripreso a fornire nuovi dati sperimentali. I dati consentiranno agli scienziati di tutto il mondo di acquisire nuovissime conoscenze sulla struttura della materia. Uno dei fisici che partecipano ai lavori è Tobias Golling (39). Il fisico delle particelle, che ha completato la sua formazione nelle città di Friburgo, Heidelberg, Bonn e al Fermilab di Chicago, dall’autunno 2014 insegna presso l’Università di Ginevra con il titolo di «Associate Professor» ed è uno dei ricercatori dell’esperimento ATLAS per LHC. Secondo Golling i dati che l’LHC fornirà nei prossimi mesi e anni potrebbero far compiere un importante passo avanti alla concezione del mondo della fisica moderna.
Premio CHIPP 2015
Cosa sia a tenere insieme il mondo nell’intimo suo essere è la domanda che si pone Heinrich Faust, l’erudito protagonista della famosa opera teatrale di Johann Wolfgang von Goethe. Per trovare una risposta Faust si dà addirittura alla magia. Anche Lilian Witthauer di Basilea, esperta in fisica delle particelle, si occupa di quest’importante domanda nella sua tesi di dottorato e ha trovato le risposte non con l’aiuto della magia ma con esperimenti approfonditi sugli acceleratori di elettroni. Per l’ottima qualità del suo lavoro scientifico è stata insignita il 29 giugno con il premio CHIPP 2015.
200 anni SCNAT
Quest'anno l’accademia svizzera di scienze naturali (SCNAT) festeggia i 200 anni dalla sua costituzione. In occasione dell'evento sarà proiettato in agosto e settembre il film "La particella di Dio" sulla scoperta del bosone di Higgs, in tre città svizzere. La particella "trovata" nel 2012 al Cern di Ginevra è una delle scoperte scientifiche più spettacolari degli ultimi anni.
Hawking-Film: "La teoria del tutto"
Quando la scienza approda sul grande schermo, l'intento solitamente è di stupire il pubblico con grandi effetti speciali. Diverso il taglio dato alla pellicola inglese "La teoria del tutto", un film biografico sulla vita dell'astrofisico Stephen Hawking e sul suo rapporto con la prima moglie Jane, diretto da James Marsh e basato sulla sceneggiatura di Anthony McCarten. Il film narra il progressivo decadimento fisico del protagonista affetto da sclerosi laterale amiotrofica o SLA, e sottolinea come la moglie sopporti enormi sacrifici per curare il marito, fino al limite delle sue forze, e come gli rimanga fedele.
Palco di Ginevra
La tavola rotonda di mercoledì 10 dicembre con Ruth Durrer (professoressa di fisica all'Università di Ginevra) e con l'artista ginevrino Christian Gonzenbach prometteva di essere costruttivo e appassionato. La promessa è stata mantenuta. Il dibattito, dal titolo "Materia oscura - l'invisibile esiste", è stato moderato da Elisabeth Chardon, giornalista del quotidiano 'Le Temps'.
Les positrons gardent encore leur secret
Grâce à l'expérience AMS pour la mesure du rayonnement cosmique, les astrophysiciens espèrent en découvrir plus sur la mystérieuse matière noire dont notre univers doit être gorgé mais dont la nature demeure inexpliquée. Les derniers résultats de l'expérience AMS ne fournissent pas encore de découverte décisive, mais ils apportent, avec la participation de l'université de Genève, un aperçu dans le rayonnement cosmique d'une précision inconnue jusqu'à présent.
Particle Fever - il dibattito
Allo Swiss Science Center Technorama di Winterthur il fisico del CERN Hans Peter Beck, lo specialista in scienze della comunicazione Mike Schäfer e la psicologa sociale Clara Kulich hanno discusso sulle possibilità e sui limiti dell'insegnamento della fisica delle particelle al grande pubblico. Il dibattito ha preso spunto dal film-documentario sulla scoperta del bosone di Higgs "Particle fever" del regista americano Mark Levinson. La prima del film per la Svizzera tedesca è stata proiettata il 1° ottobre 2014 nell'Auditorium del Technorama.
Una visita agli eredi di Einstein: film 'Particle Fever'
Com'è la vita dei fisici moderni? A questa domanda cerca di rispondere Mark Levinson con il suo documentario "Particle Fever". La prima del film per la Svizzera tedesca sarà proiettata questo mercoledì nel Swiss Science Center Technorama di Winterthur. Abbiamo visto il film in anteprima. Una recensione.
Débat Neuchâtel
Le CERN à Meyrin près de Genève ou le projet Human Brain sur l'Arc lémanique sont deux paquebots qui concentrent de nombreux scientifiques et des moyens financiers importants. Au détriment de quoi ? La question a été débattue lors d'un débat à Microcity à Neuchâtel.
Eduard Kaser sulla Big Science
Il nuovo polo tecnologico Microcity è stato inaugurato a maggio 2014 a Neuchâtel. Il centro di ricerca, fortemente voluto dal Cantone di Neuchâtel e dal Politecnico di Losanna, aspira a divenire un centro di competenza nell’ambito della microtecnologia. Ma come si colloca Neuchâtel rispetto ai grandi progetti di ricerca come il Laboratorio europeo di fisica delle particelle di Ginevra (CERN) o lo Human brain project (Hbp), il progetto «faro» sul cervello umano finanziato dall'Unione europea e diretto dal Politecnico federale di Losanna? Ne parliamo con il dr. Eduard Kaeser, pubblicista scientifico di Berna.
Dibattito sul CERN
Durante la riunione annuale congiunta dell'Istituto Svizzero di Fisica delle Particelle (CHIPP) e della Società Svizzera di Fisica (SPS), è stato indetto il 2 luglio all'Università di Friburgo un dibattito con ospiti illustri che hanno discusso sull'"influenza del CERN sulla Svizzera e sulla società svizzera". In occasione del sessantesimo anniversario del Laboratorio europeo di fisica delle particelle (CERN), il dibattito ha trattato il tema dei grandi vantaggi così come delle opportunità mancate.
CHIPP Prize 2014
ETH doctoral candidate Marco Peruzzi has been awarded the CHIPP prize 2014 at the CHIPP annual meeting in Fribourg. The 26-year old physicist of Italian descent analyses the so called diphoton decay in the CMS experiment at CERN. His research is a valuable contribution to a better understanding of the Higgs-particle.
60 ans CERN
Olivier Schneider, prof. de physique des particules élémentaires à l'Ecole polytechnique fédérale de Lausanne (EPFL), est le président du 'Swiss Institute of Particle Physics', l'organisation qui comprend tous les physiciens des particules travaillant en Suisse. A l'occasion du 60ème anniversaire du CERN, Olivier Schneider explique l'importance du CERN pour la société suisse.
Auf der Suche nach dem 'sterilen' Neutrino
In wenigen Monaten startet am Fermilab bei Chicago (USA) ein aufsehenerregendes Experiment, mit dem Physiker abklären wollen, ob neben den drei bekannten Typen von Neutrinos ein vierter Typ besteht. Bemerkenswert an diesem Experiment ist auch die personelle Zusammensetzung der Kollaboration: Die rund 120 beteiligten Forscherinnen und Forscher stammen vorwiegend aus den USA, aber die wissenschaftliche Leitung des Experiments obliegt aber einem Schweizer, nämlich dem Berner Physikprofessor Michele Weber.
Katmandu chiama
Nel ricco Occidente la ricerca e la didattica universitaria sono un'ovvietà: in questi paesi esiste un ampio spettro di istituti per tutte le possibili discipline del sapere. Invece, nei paesi in via di sviluppo l'istruzione rimane ancora spesso un bene che scarseggia. Ciò vale anche per la fisica delle particelle. I rappresentanti del Laboratorio europeo di fisica delle particelle (CERN) di Ginevra si sono mossi con un'iniziativa privata per diffondere anche in Nepal l'amore per questa disciplina fondamentale.
L'expérience BOSS
Seuls quatre pour cent de notre univers se composent de matière inconnue. En revanche, la physique moderne est convaincue que la majeure partie de l'univers se compose d'énergie noire. Personne ne peut encore vraiment expliquer ce qu'est cette énergie noire. Un astrophysicien de l'ETH de Lausanne (EPFL) fournit quelques indices pour une meilleure compréhension du phénomène : le jeune chercheur de 26 ans Timothée Delubac analyse des données du ciel étoilé qui devraient permettre une meilleure compréhension de l'énergie noire à l'avenir. Au cours de derniers mois, Delubac a acquis de nouvelles connaissances fascinantes dans le cadre de l'expérience BOSS.
Kosmische Strahlung aus noch unbekannter Quelle
Seit dem 19. Mai 2011 ist das Alpha Magnetic Spektrometer (AMS) auf der Internationalen Raumstation ISS in Betrieb. Das Hightech-Messgerät funkt seither ständig Messdaten über die kosmische Strahlung zur Erde. Nach knapp zwei Jahren macht das Experiment mit spektakulären Ergebnissen auf sich aufmerksam.
Dibattito Liceo di Locarno
Ma serve? La domanda è legittima. Miliardi di franchi investiti per scoprire una nuova particella e…? Già: e poi? Che cosa ne deriva per il miglioramento della vita delle persone? Insomma, a che serve la fisica? Quali ricadute ha nell’ambito della medicina, per esempio? Proprio di questo hanno discusso per un paio d’ore, nel pomeriggio di venerdì 4 aprile, Martina Bucciantonio e Franco Cavalli, moderati dal giornalista Gerhard Lob, in un appassionante confronto dal titolo “Materia viva o materia morta - La ricerca in medicina, la ricerca in fisica”, davanti a una cinquantina di studenti di quarta del Liceo di Locarno.
Neutrino
Ogni dubbio è fugato: i neutrini muonici possono trasformarsi in neutrini tauonici. Gli scienziati impegnati nell'esperimento OPERA che si svolge nei laboratori sotterranei del Gran Sasso in Italia, e vede tra gli altri la collaborazione dei fisici dell'Università di Berna, hanno dimostrato questo fenomeno con una precisione finora sconosciuta. Il risultato è stato presentato nell'ambito di un seminario scientifico ai Laboratori Nazionali del Gran Sasso.
Gravitationswellen-Signal von Big Bang entdeckt
Einem internationalen Forscherteam ist mit dem Mikrowellenteleskop Bicep2 am Südpol der Nachweis von Gravitationswellen gelungen. Dies gaben die Wissenschaftler am Montag bekannt. Hält diese Nachricht einer unabhängigen Überprüfung stand, handelt es sich um eine der spektakulärsten Entdeckungen der modernen Physik. Damit würden erstmals die Gravitationswellen experimentell nachgewiesen, die Albert Einstein in seiner Relativitätstheorie vorausgesagt hatte. Im Interview erläutert die an der Universität Genf tätige Kosmologin Ruth Durrer die Hintergründe.
Protonterapia
In Svizzera sono relativamente poche le giovani donne che studiano fisica. Diversamente in Italia, dove lo studio della fisica per le donne è una cosa che avviene più con naturalezza. Non è un caso, quindi, che è stato un fisico italiano donna Fabiola Gianotti che a nome dell'esperimento ATLAS al CERN ha annunciato nel Luglio 2012 la scoperta della particella di Higgs. Anche Martina Bucciantonio è un fisico italiano, e anche lei lavora al CERN. All'inizio della sua carriera la giovane scienziata si è occupata soprattutto di questioni fondamentali, tra cui l'analisi dei dati. Ora nella sua tesi di dottorato si dedica alle applicazioni mediche della fisica. Il 4 aprile Martina Bucciantonio prenderà parte ad un dibattito al Liceo cantonale di Locarno con il noto oncologo Franco Cavalli sul tema: "Materia viva o materia morta - La ricerca in medicina, la ricerca in fisica."
Was die Teilchenphysik heute weiss
Dr. Hans Peter Beck, Privatdozent für Physik an der Universität Bern und Teilchenphysiker am Europäischen Labor für Teilchenphysik (CERN) in Genf gewährt in einem Interview mit der Webplattform Xecutives.net Einblick in das Weltbild der modernen Physik. Er erläutert die Hintergründe, die 2012 zur Entdeckung des Higgs-Teilchens führten, er spricht über die Geheimnisse der Dunklen Materie und erklärt aus seiner Sicht, was Physik und Mathematik verbindet.
Future Circular Collider
The Higgs boson was discovered in the particle accelerator LHC (Large Hadron Collider) at CERN in 2012 – and scientists are expecting to gain more groundbreaking insights from this large research facility in Geneva during the next twenty years of its operation. Nevertheless physicists are already working meticulously on a new and even bigger accelerator with the name FFC that shall make particle collisions of even higher energy possible. Stefan Antusch, Professor for Theoretical Physics at the University of Basel, explains the state and the aim of this new project.
Top-Quark
Sieht man vom Higgs-Teilchen ab, war das Top-Quark das letzte Elementarteilchen des heute gültigen Standardmodells, das experimentell nachgewiesen wurde. Dieser Nachweis gelang 1995 am Fermilab unweit von Chicago/USA. Wissenschaftlern dieser Forschungseinrichtung ist nun eine weitere Entdeckung rund um das Top-Quark gelungen: Sie haben einen neuen, sehr selten zu beobachtenden Weg experimentell nachgewiesen, auf dem das Top-Quark erzeugt werden kann.
Debatte Brugg
Teilchenphysikerinnen und Teilchenphysiker leisten mit ihrer Forschung einen Beitrag zum Verständnis der Welt. Sie tragen aber oft auch bei zur Weiterentwicklung der Wirtschaft durch innovative Produkte. Diesen Aspekt hat am 12. Februar 2014 eine Podiumsdebatte am Hightech Zentrum Aargau in Brugg beleuchtet, an der Roland Horisberger, ETH-Professor und Leiter der Hochenergiephysik am Paul Scherrer Institut in Villigen/AG, mit Wirtschaftsvertretern diskutierte. Am 23. April 2014 fand mit den Teilnehmern eine Internetdiskussion (Hangout) zum gleichen Thema statt (die Aufzeichnung finden Sie auf dieser Seite ganz unten). Podiumsgespräch und Hangout waren Veranstaltungen im Rahmen des vom Schweizerischen Nationalfonds geförderten Projekts 'Interactions'.
Proton accelerator
Materials research, particle physics, molecular biology, archaeology – for the last forty years, the Paul Scherrer Institute’s large-scale proton accelerator has made top-flight research possible in a number of different fields. Initially, it was supposed to help clarify issues in particle physics by producing pions. Later, the facilities around the accelerator were expanded so that its proton beam could also be used to generate neutrons and muons for a wide range of experiments – frequently in research fields that nobody had even considered during the construction of the plant. Today, about twenty experiments can take place simultaneously here. The PSI’s large proton accelerator currently delivers the most powerful proton beam in the world. The experience that the researchers and engineers at the PSI have gained at the facility also formed the basis for the development of proton therapy, which has already been used to treat several thousand cancer patients successfully at the PSI.
