Understanding the branching ratios of \chi_{c1} \rightarrow \phi\phi, \omega\omega, \omega\phi observed at BES III

In this work, we discuss the contribution of the mesonic loops to the decay rates of cc1 ff, ww which are suppressed by the helicity selection rules and cc1 fw which is a double-OZI forbidden process. We find that the mesonic loop effects naturally explain the clear signals of cc1ff, ww de…
