Description
A precision measurement of the helicity-suppressed ratio RK of the K+- --> e+- nu and K+- --> mu+- nu decay rates has been performed using the full data set collected by the NA62 experiment in 2007--2008. The result is in agreement with the Standard Model expectation, and constrains two-Higgs-voublets extension of the Standard Model.
