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.

Particle Physics Strengthens the Industrialized Country of Switzerland

Particle physics is a basic science that forms our image of matter and the universe. However, the findings of this discipline also have practical applications that directly influence our daily lives. One example is the company DECTRIS AG in Baden-Dättwil. At the joint annual conference of the Austrian Physics Society (ÖPG), the Swiss Physical Society (SPS) and the Swiss Institute for Particle Physics (CHIPP) in Geneva in August, the company presented its latest business ventures.

CHIPP Prize 2017 goes to Johanna Gramling

The experimental detection of dark matter is one of the great challenges of current fundamental research in physics. This year’s prize of the Swiss Institute of Particle Physics (CHIPP) is awarded to the physicist Dr. Johanna Gramling for her latest contributions to the search for this mysterious component of matter.

T2K presents hint of CP violation by neutrinos

The international T2K Collaboration strengthened its previous hint that the symmetry between matter and antimatter may be violated for neutrino oscillation.

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.
