Abstract
Bottomoniumlike resonances and are good candidates to be hadronic molecules composed of (or ) and , respectively. In this paper, considering as heavy meson molecules, we investigate the decays of in terms of the heavy meson effective theory. We find that the intermediate and meson loops and the form factors play a significant role in reproducing the experimental values of the decay widths. We also predict the decay widths of and for a charmoniumlike resonance , which has recently been reported in experiments.
