Title: Search for heavy neutrinos in K + μ + ν H decays

Abstract

Here, evidence of a heavy neutrino, ν H, in the K +→μ +ν H decays was sought using the E949 experimental data with an exposure of 1.70 × 10 12 stopped kaons. With the major background from the radiative K +→μ +ν μγ decay understood and suppressed, upper limits (90% C.L.) on the neutrino mixing matrix element between the muon and heavy neutrinos, |U μH| 2, were set at the level of 10 –7 to 10 –9 for the heavy neutrino mass region 175 to 300 MeV/c 2.
