Query: Study of the psi(2S) decay to p pbar pi+ pi-   The branching ratios of psi(2S)-->p pbar Pi+ pi- and psi(2S)-->p pbar omega,
omega--> pi+ pi- pi0 are measured and the pi+ pi- invariant mass distribution
in the first decay is discussed by analyzing
  14 million produced psi(2S) events collected by the BESII detector at the
BEPC.
