Novel technique to measure Lepton Universality ratio $R_K$ at NA62
Lepton universality is one of the key properties of the Standard Model. In the kaon sector, lepton universality is tested measuring the ratio $R_K = \Gamma(K^+\to e^+ \nu(\gamma))/ \Gamma(K^+ \to \mu^+ \nu (\gamma))$, which has a very precise theoretical prediction. $R_K$ has been measured collectin...
