Abstract
We study the semileptonic decays of , in which the three states mix with glueball, , and states, respectively. By averaging the mixings fitted in the literature, we find that the branching ratios of are , , and , respectively, which can be simultaneously observed in experiments at factories. The large predicted branching rate for would provide a clean mode to directly observe the state.
