摘要：

The HyperCP experiment (Fermilab E871) has the largest recorded sample of Omega(-) hyperon decays, allowing new searches for three rare decay modes, each with five charged tracks in the final state. Results axe presented for Omega(-) --> Xi(-)pi(+)pi(-);Omega(-) --> Xi(0) (1530)pi(-); and the flavor-changing neutral-current decay Omega(-) --> Xi(-)mu(+)mu(-). Normalization of these measurements. were to the decay Omega(-) --> LambdaK(-) with a five-track topology similax to the signal mode with the subsequent decay of Lambda --> ppi(-) and K- --> pi(-)pi(+)pi(-) in the decay volume.
