Measurements of J/psi decays into phi pi0, phi eta, and phi etaprime
Abstract
Based on 5.8x107 J/psi events detected in BESII, the branching fractions of J/psi--> phi eta and phi etaprime are measured for different eta and etaprime decay modes. The results are significantly higher than previous measurements. An upper limit on B(J/psi--> phi pi0) is also obtained.
