Exploring new physics with flavour

Jul 2, 2026, 9:00 AM → Jul 3, 2026, 8:00 PM Europe/Berlin

Physics Highrise building

Martina Schorn, Matthias Steinhauser (KIT), Tim Kretz

The workshop covers the phenomenology of flavour physics observables in the Standard Model and beyond. Topics include precision calculations as well as studies of generic BSM physics and concrete theories of new physics. The event ends with the festive colloquium  organised by the Faculty of Physics of KIT for Ulrich Nierste on the occasion of his 60th birthday.

Topics:

• Meson-antimeson mixing in the SM and beyond
• Precision calculations for K, D, and B decays 
• Rare decays in theories of new physics
• Extended Higgs sectors in flavour and collider physics
• Leptoquarks in flavour and collider physics
