The NA62 experiment at the CERN SPS aims at measuring the branching ratio (BR) of the rare K+ â Ï +vvÌ decay, with a precision of â ¼ 10%. This goal will be achieved after two years of data taking by collecting â ¼ 1013 K+ decays in the fiducial volume. The K+ â Ï +vvÌ is a "golden mode" in flavor physics because of the precise theoretical prediction. Thanks to the unprecedent kaon flux, it will also be possible to search for many other forbidden processes, including leptor flavor violation modes, sterile neutrinos, supersymmetric particles. The expected NA62 performances will wallow the exclusion limits for several decay modes to be improved. The experiment will start collecting data in late 2014.
