Precision Measurement of the Ratio of the Charged Kaon Leptonic Decay Rates
A precision measurement of the ratio $R_K$ of the rates of kaon leptonic decays $K^\pm \to e^\pm\nu$ and $K^\pm \to \mu^\pm \nu$ with the full data sample collected by the NA62 experiment at CERN in $2007-2008$ is reported. The result, obtained by analysing $\sim\!150000$ reconstructed $K^\pm \to e^...
