Abstract
Searches for heavy neutral lepton production in K+→e+N and K+→μ+N decays using the data set collected by the NA62 experiment at CERN in 2016-18 are presented. Upper limits on the elements of the extended neutrino mixing matrix and are established at the levels of and , respectively, improving on the earlier searches for heavy neutral lepton production and decays in the kinematically accessible mass range. Searches for the K+→μ+ννν¯ and K+→μ+νX decays, where X is an new light invisible particle, are also reported.
