Abstract

The decay is one of the theoretically cleanest meson decays to look for indirect effects of new physics in a complementary way to direct searches at the LHC. The NA62 experiment at CERN SPS is designed to measure the branching ratio of this decay with 10% precision. NA62 is taking data since 2014, eventually reaching the final designed beam intensity. Using a sample of data taken in 2015, the experimental performances in view of the branching ratio measurement is reported.

  • The K+ → π+ννand KL → π0ννare flavour changing neutral current decays proceeding through box and electroweak penguin diagrams

  • The knowledge of the external inputs dominate the uncertainties on the predictions
