Particle Physics

Particle physics deals with questions such as what matter is made of and what determines its properties and its interactions. The answers give information on how the universe began and how it might evolve in the future.

Particle physics addresses these fundamental questions at the smallest length scales, either in particle production in high energy collisions or other reactions such as particle decays. The present knowledge on the known elementary particles is summarized in the so-called Standard Model.


Research Interests

Effective Field Theories: Soft Collinear Effective Theory (SCET) for the treatment of high energy jets, Chiral Perturbation Theory (CHPT) describing the low-energy limit of Quantum Chromodynamics (QCD).
Quark Flavour Physics: Physics of B mesons and Kaons.
Neutrino Physics: Fieldtheoretical models for neutrino masses and lepton mixing and phenomenological consequences.
New Physics: Extensions of the Standard Model.
Supersymmetry: Search for SUSY particles and their effects in flavour physics and CP violation.
Dynamical systems: Active motion.


Recently, a new particle has been discovered at the LHC experiment which has properties consistent with the so-called Higgs boson. Further investigations will clarify whether the new particle is indeed the Higgs boson and whether we understand correctly the mechanism behind matter manifesting itself in massive objects. Particle physics also searches for deviations from the Standard Model predictions which would indicate exciting new physics to be explored. Investigations of neutrinos should soon be able to uncover their intrinsic nature (Majorana vs. Dirac). Collider experiments at lower energies but with very high precision allow to test the flavour structure of elementary particles and to search for new physics indirectly
