Measurement of chi_cJ Decays to 2(pi^+pi^-)ppbar Final States

Abstract

Using chi_cJ -> 2(π^+π^-) ppbar decays from 14 \times 10^6 psi(2S) events accumulated by the BESII detector at the BEPC, the intermediate states Xi^+Xi^-, Lambda Lambdabar pi^+ pi^-, and K_SK_S p pbar are studied, and their branching ratios or upper limits are measured.
