Abstract
Using a sample of 2.59x10(7) psi(2S) decays collected by the CLEO-c detector, we present results of a study of chi(cJ) (J=0, 1, 2) decays into baryon-antibaryon final states. We present the world's most precise measurements of the chi(cJ)-> p (P) over bar and chi(cJ)->Lambda(Lambda) over bar branching fractions, and the first measurements of chi(c0) decays to other hyperons. These results illuminate the decay mechanism of the chi(c) states.
