摘要

The decays of the psi(2S) into vector plus tensor meson final states have been studied for the first time using the BES detector. We determine upper limits on branching fractions for psi(2S) decays into omega f(2), pa(2), + c.c., and phi f(2)'(1525) that are, in each case, significantly smaller than the corresponding branching fractions for the J/psi meson, scaled according to the expectations of perturbative QCD.
