Description
The NA48 at CERN has recently published a limit on the presence of heavy neutrinos from decays of charged kaons into a pion and muons. The following NA62 experiment at CERN collected a large sample of charged kaon decays in flight with a minimum bias trigger in 2007. Upper limits on the rate of the charged kaon decay into a muon and a heavy neutral lepton (HNL) obtained from this data are reported for a range of HNL masses. The NA62 experiment has collected further data in 2015 with a completely new and improved detector. New limits on heavy neutrinos from kaon decays into pion, electron and positron will be presented.
