A sensitive search for the lepton-number-violating decay Xi(-)--pmu(-)mu(-) has been performed using a sample of approximately 10(9) Xi(-) hyperons produced in 800 GeV/c p-Cu collisions. We obtain B(Xi(-)--pmu(-)mu(-))4.0x10(-8) at 90% confidence, im

A sensitive search for the rare decays Omega(-)--Lambdapi(-) and Xi(0)--ppi(-) has been performed using data from the 1997 run of the HyperCP (Fermilab E871) experiment. Limits on other such processes do not exclude the possibility of observable rate

We report the first evidence for the decay Sigma(+)--pmu(+)mu(-) from data taken by the HyperCP (E871) experiment at Fermilab. Based on three observed events, the branching ratio is B(Sigma(+)--pmu(+)mu(-))=[8.6(+6.6)(-5.4)(stat)+/-5.5(syst)]x10(-8).

We have compared the p and p angular distributions in 117 x 10(6) Xi- --Lambdapi- --ppi-pi- and 41 x 10(6) Xi+ --Lambda pi+ --p pi+pi+ decays using a subset of the data from the HyperCP experiment (E871) at Fermilab. We find no evidence of CP violati

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 measurements of the branching ratios for K+/---pi(+/-)mu(+)mu(-). By comb
