Elementary Particle Physics

Our group experimentally studies the properties of elementary particles and their interactions. These are described by the so called standard model of particle physics. The standard model explains many questions about the structure and stability of matter with its six kinds of quarks and leptons and their four interactions.

Nevertheless many questions still remain unanswered:

  • Why are there three families of quarks and leptons?
  • Is there an explanation for the mass difference of quarks and leptons?
  • Are there even more particles or interactions that have not been discovered yet?
  • Are quarks and leptons really fundamental particles or do they have a substructure?
  • How does gravitation fit into the standard modell?
Our group contributes in various projects in the following areas:
