Abstract

c Copyright owned by the author(s) under the terms of the Creative Commons The NA62 experiment at the CERN SPS recorded in 2007 a large sample of K + ? µ + ? µ decays. A peak search in the missing mass spectrum of this decay is performed. In the absence of observed signal, the limits obtained on B(K + ? µ + ? h ) and on the mixing matrix element |U µ 4 | are reported. The upgraded NA62 experiment started data taking in 2015. About 5×10 11 K + decays have been recorded so far to measure the branching ratio of the K + ? ? + ?? decay. Preliminary results from the K + ? ? + ?? analysis based on about 5% of the 2016 statistics are reported.
