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.

“Strange animals” in the spotlight
When protons or ions collide with targets or each other, they produce lots of new particles. Some of these are wanted, some are unwanted, but whatever their desired status – they need to be well understood. Neutrons, which belong to these products, are a particular challenge. Their characteristics such as their energy, direction and number are a pain to measure, but knowing them well brings many advantages to various branches of science and its applications. A novel experimental approach based on a new neutron spectrometer recently tested by members of the Laboratory for High-Energy Physics at the University of Bern in collaboration with Politecnico di Milano and its spin-off company Raylab yields promising results that appear to be even more versatile than expected.

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?
