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…

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…

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…
