Large isospin symmetry violation in kaon production?

Published online: 26 June 2024
The recent measurements of kaon production in Ar+Sc collisions at 75A GeV/c (√SNN = 11.94 GeV) performed by NA61/SHINE at the CERN SPS resulted in determining the ratio of charged to neutral kaons to be 1.26 ± 0.06. The result, well above unity, cannot be explained by models accounting for known isospin symmetry violating processes. This contribution will present the experimental details of this intriguing result. It will also compare it to the world data on charged to neutral kaon ratio in nucleus-nucleus collisions.
