12th International Workshop on the CKM Unitarity Triangle (CKM 2023)

18 Sept 2023, 06:00 → 22 Sept 2023, 18:00 Europe/Madrid

Veronika Georgieva Chobanova (Universidade de Santiago de Compostela (ES))

CKM 2023 is the 12th International Workshop on the CKM Unitarity Triangle, to be held September 18 to 22, 2023 in Santiago de Compostela, Spain.

The CKM series is a well-established international meeting in the field of quark-flavour physics that brings together experimentalists and theorists to a common platform. The program covers neutron, kaon, charm and beauty hadron, top quark physics and lepton flavour violating Higgs.
