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…
Improved Spin Dependent Limits from the PICASSO Dark Matter Search Experiment
The PICASSO Collaboration, M. Barnabe-Heider, E. Behnke +18
The PICASSO experiment reports an improved limit for the existence of cold dark matter WIMPs interacting via spin-dependent interactions with nuclei. The experiment is installed in…
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…
