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.

Einsteins Wunderjahr 1905 und die moderne Physik

Im Jahre 1905 verfasste das Jahrhundert-Genie Albert Einstein sechs grundlegende Arbeiten in drei verschiedenen Gebieten. Die Themen- bereiche betreffen 1) die Quantentheorie, 2) die Wärmelehre oder Thermodynamik und 3) die relativistische Mechanik, bekannt als Relativitätstheorie.

Visiting the Japanese Super-Kamiokande detector (part 2)

In deep underground tunnels of former mines near the Japanese Alps, teams of scientists with Swiss participation are researching various types of elementary particles. Over the next few years, powerful research instruments will be put into operation with which scientists want to discover the nature of neutrinos. The hoped-for results could lead to solving of deep puzzles in our understanding of the universe.

Visiting the Japanese Super-Kamiokande detector (part 1)

Hardly any elementary particle occurs more frequently in the universe than the elusive neutrino. The investigation of the almost massless tiny particle is a focus of current elementary particle physics. Perhaps the most important contribution to the understanding of neutrino has been made over twenty years by the Japanese Super-Kamiokande detector, in which several Swiss research groups are involved.

Was ist Licht? Erkenntnisse der Quantenphysik

Die Quanteneigenschaften des Lichts lassen sich als Werkzeug nutzen für eine radikal neue Quantentechnologie.

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.
