CPPS mini-workshop on Vcb and CKM

28 Oct 2025, 08:00 → 29 Oct 2025, 19:00 Europe/Berlin

University Siegen

The purpose of this mini-workshop is to bring together theorists and experimentalists working on the extraction of CKM elements, with a particular focus on Vcb, to discuss important issues regarding both high- and low-energy aspects.

 

The mini-workshop will cover theoretical and experimental aspects of the following topics:

• Vxb extraction from HEP data

• Vxb extraction from B-physics

 

Participants will have to book their own accommodation. Please see Accommodation for detailed information.
