Kaon experiments at CERN: recent results and prospects

Mostrar otras versiones (1)

Recent results from the NA48/2 and NA62 kaon decay-in-flight experiments at CERN are presented. A precision measurement of the helicity-suppressed ratio RK of the K+- to e+- nu and K+- to mu+- nu decay rates has been performed using the full dedicated data set collected by the NA62 experiment (RK ph...

description Recent results from the NA48/2 and NA62 kaon decay-in-flight experiments at CERN are presented. A precision measurement of the helicity-suppressed ratio RK of the K+- to e+- nu and K+- to mu+- nu decay rates has been performed using the full dedicated data set collected by the NA62 experiment (RK phase); the result is in agreement with the Standard Model expectation. New measurements of the K+- to pi+- gamma gamma decay at the NA48/2 and NA62 experiments provide further tests of the Chiral Perturbation Theory. A planned measurement of the branching ratio of the ultra-rare K+ to pi+ nu anti-nu decay at 10% precision is expected to represent a powerful test of the Standard Model.
