Search for the Lepton-Number-Violating Decay
HyperCP Collaboration, D. Rajaram, R. A. Burnstein +28
A sensitive search for the lepton-number-violating decay has been performed using a sample of hyperons produced in 800 GeV/ -Cu collisions.…
Observation of Parity Violation in the Omega-minus -> Lambda + K-minus Decay
HyperCP Collaboration, L. C. Lu, R. A. Burnstein +28
The alpha decay parameter in the process Omega-minus -> Lambda + K-minus has been measured from a sample of 4.50 million unpolarized Omega-minus decays recorded by the HyperCP (E87…
delta S = 2 nonleptonic hyperon decays
C. G. White, R. A. Burnstein, A. Chakravorty +32
A sensitive search for the rare decays Ω^- \to Λπ^- and Ξ^0 \to p π^- has been performed using data from the 1997 run of the HyperCP (Fermilab E871) experiment. Limits on other suc…
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…
Search for CP Violation in Charged-Xi and Lambda Hyperon Decays
HyperCP Collaboration, T. Holmstrom, N. Leros +35
We have compared the proton and antiproton angular distributions in 117 million Xi-minus -> Lambda + pi-minus -> proton + pi-minus + pi-minus and 41 million anti-Xi-minus -> anti-L…
High Statistics Search for the Theta+(1.54) Pentaquark State
M. J. Longo, R. A. Burnstein, A. Chakravorty +30
We have searched for Theta+(1.54) -> K0,p decays using data from the 1999 run of the HyperCP experiment at Fermilab. We see no evidence for a narrow peak in the K0,p mass distribut…
