Search for the Lepton-Number-Violating Decay $Ξ^{-} \to p μ^{-} μ^{-}$

HyperCP Collaboration, D. Rajaram, R. A. Burnstein +28

A sensitive search for the lepton-number-violating decay $Ξ^{-} \to p μ^{-} μ^{-}$ has been performed using a sample of $\sim 1 0^{9}$ $Ξ^{-}$ hyperons produced in 800 GeV/ $c$ $p$ -Cu collisions.…

Evidence for the Decay Sigma+ -> p mu+ mu-

H. K. Park, R. A. Burnstein, A. Chakravorty +30

We report the first evidence for the decay Sigma+ -> p mu+ mu- from data taken by the HyperCP experiment(E871) at Fermilab. Based on three observed events, the branching ratio is B…
