abstract

  • 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 |Uµ 4| are reported. The upgraded NA62 experiment started data taking in 2015. About 5×1011K 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%25 of the 2016 statistics are reported. c Copyright owned by the author(s) under the terms of the Creative Commons
