Particle Physics

Particle physics probes the basic building blocks of matter and their interactions, which determine the structure and properties of the extreme diversity of matter in the universe. It aims at explaining what holds the world together in its most fundamental constituents.

Modern physics relies on an elegant «Standard Model of particle physics», a quantum field theory based on three symmetries and a symmetry breaking. This theory describes and explains magnificently all experimental results obtained so far. With the discovery of the Higgs particle in 2012 at the Large Hadron Collider at CERN, the last missing piece of the Standard Model has been experimentally confirmed. Experiments at CERN and at other international laboratories now continue to test the validity and limits of the Standard Model in ever widening scope. However, for a comprehensive understanding of the laws of nature a theory beyond the Standard Model is needed, which should include gravitation and explain the presence of dark matter and dark energy in the universe.

M87- Allererstes Foto eines schwarzen Loches

Das Projekt Event Horizon Telescope (EHT, dt. Ereignishorizont Teleskop) hat zum Ziel, die ersten Fotos der Umgebung der schwarzen Löcher M87* im Virgo-Cluster und Sgr A* (Sgr = Sagittarius = Schütze) im Zentrum der Milchstrasse zu machen.

The Innovation Park “PARK INNOVAARE” in Villigen (AG) supports start-up companies in the field of accelerator technology.

CERN in Geneva is the leading particle physics laboratory worldwide. Large particle accelerators based on the most innovative technologies are used there for fundamental research. One year ago, the innovation park “PARK INNOVAARE” in Villigen (AG) launched, together with CERN, the BIC of CERN program: it supports start-ups and high-tech micro-companies using CERN technologies for commercial applications. These days the second call for proposals has started.

What large-scale research facilities does Switzerland need?

The Swiss Academies of Arts and Sciences have been requested by the Confederation to prepare roadmaps for research infrastructures for the various scientific fields. These roadmaps will provide a basis for decision-making on the allocation of federal funding for costly research facilities over the period 2025–2028. SCNAT is responsible for implementing this new procedure within the Swiss Academies, and Secretary General Jürg Pfister believes that it offers the scientific community an opportunity for wider involvement.

The LHCb collaboration at CERN has discovered a type of CP violation unobserved so far

The LHCb collaboration at CERN has seen, for the first time, the matter–antimatter asymmetry known as CP violation in a so-called D0 meson. LHCb is one of the four large experiments performed at the Large Hadron Collider (LHC) with Swiss participation of Ecole polytechnique fédérale de Lausanne (EPFL) and University of Zurich.

Swiss physicists in dialog with the society

Swiss physicists want to make their fascinating research understandable to the interested public and to debate its meaning for our society together with representatives of other fields.
