Heavy neutrino searches and NA62 status Conference Paper uri icon

abstract

  • The NA62 experiment at CERN SPS recorded in 2007 a large sample of K → K%2b→μ%2bνμ 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%2b → μ%2bνh) and on the mixing matrix element |Uμ4|2 are reported. The upgraded NA62 experiment started data taking in 2015, with the aim of measuring the branching fraction of the K → → π%2bνν decay. An update on the status of the experiment is presented. © Published by ARISF, 2017.
