NA62 experiment at CERN SPS

The NA62 experiment at SPS is a continuation of the long standing CERN kaon physics program. The high statistics and the unprecedent precision allow to probe the Standard Model and test the description of the strong interactions at low energy. The final results on the the lepton universality test by measuring the ratio $R_K = Γ(K^{+}\to e^{+}ν) / Γ(K^{+}\to μ^{+}ν)$ and the study of the $K^\pm\toπ^{\pm}γγ$ decay are presented. The major goal of the NA62 experiment is to perform a measurement of the $Br(K^{+} \to π^{+} ν\barν)$ with a precision of 10% in two years of data taking. The detector setup together with the analysis technique is described.
