摘要With the recent measurements of psi' and J/psi decay into octet-baryon pairs, we study the relative phase between the strong and the electromagnetic amplitudes, and find a large phase by fitting the present data. The fits take into account the details of experimental effects, including energy spread and initial state radiation. We also predict some branching fractions of psi' decays and the continuum production rates at the J/psi mass based on the relative phase and absolute amplitudes obtained from the fits.
