Description
Searches for heavy neutral lepton (HNL) production in charged kaon
decays using the data collected by the NA62 experiment at CERN are
reported. Upper limits are established on the elements of the extended
neutrino mixing matrix for heavy neutral lepton mass in the range
130-450 MeV, improving on the results from previous HNL production
searches. The status and prospects of searches for lepton flavour and
lepton number violation in kaon decays at the NA62 experiment is also
presented.
