The NA48/2 experiment at CERN has collected large samples of charged kaons decaying into a pion and two muons for the search of heavy neutrinos. In addition, its successor NA62 has set new limits on the rate of charged kaon decay into a heavy neutral lepton (HNL) and a lepton, with = e, µ, using the data collected in 2007 and 2015. New limits on heavy neutrinos from kaon decays into pions, muons and positrons are presented in this report.

Abstract
The NA48/2 experiment at CERN has collected large samples of charged kaons decaying into a pion and two muons for the search of heavy neutrinos. In addition, its successor NA62 has set new limits on the rate of charged kaon decay into a heavy neutral lepton (HNL) and a lepton, with = e, µ, using the data collected in 2007 and 2015. New limits on heavy neutrinos from kaon decays into pions, muons and positrons are presented in this report.File in questo prodotto:
