Dear colleagues
we are sorry to share the sad news about our dear colleague Bernd. Our thoughts are with the family and friends.
The Swiss Institute of Particle Physics (CHIPP) is the bottom-up organisation of Swiss particle and astroparticle physics researchers in Switzerland as a legal entity of Swiss law. CHIPP is tasked with coordinating the national efforts in the realm of particle and astroparticle physics.
This is achieved by keeping a continuous dialogue between the particle physicists of different cantonal universities and federal institutes. CHIPP is recognized as the representative of Swiss particle physics both nationally and internationally. It awards yearly a Prize to a PhD student, supports workshops and conferences, organises PhD schools, and develops outreach projects.

Restarting the LHC: a new era of physics data
After three years of a scheduled break, the Large Hadron Collider LHC at CERN is back at full throttle, accelerating particle beams at record energies and since 5 July 2022 producing first collisions for physics analyses. Institutes from all over Switzerland have contributed to the upgrading of the enormous particle physics complex and scientists are keen to their hands on the new data it will produce in its new run.

Hopp Higgs!
Ten years ago, on 4 July 2012, the ATLAS and CMS collaborations cautiously announced the discovery of a particle “consistent with the Higgs boson” at CERN. In the end it turned out to *be* the Higgs boson, the particle that had been predicted by theorists nearly forty years earlier. What was it like to witness the announcement of one of the discoveries of the century? And what have we learned about the mysterious Higgs in the ten years since?

Making (gravitational) waves in Switzerland
In Switzerland, gravitational waves go a long way. Not only were they predicted by Albert Einstein in his famous general theory of relativity; Swiss researchers have been involved in attempts to detect gravitational waves from the very beginning and are keen to lend their expertise, including from particle physics, to future projects as well. Here’s an update about the current state of research…

Physics at fundamental Symmetries and Interactions PSI2022
The workshop focuses on the physics at the low energy, high precision frontier without neglecting complementary approaches. It aims at highlighting present activities and future developments. The Paul Scherrer Institut (PSI) itself offers unique opportunities for experiments in this realm: it houses the world's most powerful proton cyclotron and the highest intensity low momentum pion and muon beams and the ultracold neutron source.

Isotope factory and experimental arena
For cancer patients, every day counts. Imagine one could skip one step in the cancer diagnosis and treatment process and do both at the same time: finding out where the tumor is and attacking it right away. A team at the University of Bern, which runs its own medical cyclotron laboratory, is currently working on exactly that. Their cyclotron is a proper workhorse for science. During the night, it produces medical isotopes for cancer diagnostics. During the day, it sidelines as a test facility for particle physics and multi-disciplinary scientific activities.
