Description

Abstract:

Isospin symmetry is well fulfilled in the QCD vacuum, as evidenced by small mass differences of isospin partners and suppressed isospin-violating decays. Recently, the NA61/SHINE collaboration reported an unexpectedly large isospin-violating charged-to-neutral kaon ratio in Ar-Sc heavy-ion collisions (HIC). Theoretical approaches cannot describe this deviation. In this talk, we summarize the status of the kaon anomaly and present its consequences.

Important: This seminar is held in building D-11 room 104.
