摘要：

The main goal of the NA62 experiment at CERN is a study of the ultra rare decay K rtvg. The collected statistics allows to analyse other rare decays, in particular, K+ mu(+) nu mu(+)mu(-). Rare decays make it possible to experimentally investigate one of the aspects of the Standard Model, the chiral perturhative theory (ChPT). ChPT predicts decay probability of K+mu(+) nu mu(+)mu(-) :1.35 x 10(-8) x ltr. This decay channel is also of great interest due to the fact, that it was not experimentally observed, there is only an upper limit < 4.1 x 10(-7) CL 90%. We present the research methodology, the first results of signal selection and the study of the background sources for the decay.
