Abstract

A search for heavy neutral lepton (HNL) production in charged kaon decays using a data sample collected with a minimum bias trigger by the NA62 experiment at CERN in 2015 is reported. Upper limits are established on the elements of the extended neutrino mixing matrix for HNL mass in the range 170−448 MeV/c2. This improves on the results from previous HNL production searches, setting more stringent limits and extending the mass range.
