Study of the rare hyperon decay Omega \to Xi π^+ π^-
HyperCP Collaboration, O. Kamaev, N. Solomey +30
We report a new measurement of the decay Ω^- \to Ξ^- π^+ π^- with 76 events and a first observation of the decay Ω^+ \to Ξ^+ π^+ π^- with 24 events, yielding a combined branching r…
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…
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…
Observation of the Decay K- -> pi- mu+ mu- and Measurements of the Branching Ratios for K+/- -> pi+/- mu+ mu-
H. K. Park
Using data collected with the HyperCP (E871) spectrometer during the 1997 fixed-target run at Fermilab, we report the first observation of the decay K- -> pi- mu+ mu- and new measu…
