Search for the rare decay $$K^+\to\mu^+\nu\bar\nu\nu$$
Abstract
We searched for evidence of the K+→μ+ $$v\bar{ν}v$$ decay using E949 (Brookhaven National Laboratory, USA) experimental data with an exposure of 1.70×1012 stopped kaons. The data sample is dominated by the background process K+→μ+νμγ. An upper limit on the decay rate Γ(K+→μ+ $$v\bar{ν}v$$) <2.4×10$$-$$6Γ(K+→all) at 90% confidence level was set assuming the standard model muon spectrum. The data are presented in such a way as to allow calculation of rates for any assumed μ+ spectrum.
