Search for heavy neutrino in decay at ISTRA+ setup

Heavy neutrino nu h with m h [lap] 300 MeV / c 2 can be effectively searched for in kaon decays. We put upper limits on a mixing matrix element | U mu h | 2 for radiatively decaying nu h from K - arrow right mu - nu h ( nu h arrow right nu gamma ) decay chain in the following parameter region: 30 Me...
