Abstract
Using 58Ã106J/Ï events collected with the Beijing Spectrometer (BESII) at the Beijing Electron Positron Collider (BEPC), the branching fractions of J/Ï to pp¯η and pp¯ηⲠare determined. The ratio Î(J/Ïâpp¯η)Î(J/Ïâpp¯) obtained by this analysis agrees with expectations based on soft-pion theorem calculations.
