Search for heavy neutral lepton production at the NA62 experiment.
In: The European Physical Society Conference on High Energy Physics, 2021-7-26 - ?.
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 10-9 and 10-8, respectively, improving on the earlier searches for heavy neutral lepton production and decays in the kinematically accessible mass range. Searches for the K+ ? µ+vvv and K+ ? µ+vX decays, where X is a new light invisible particle, are also reported.
