Heavy quark hybrid decays
Keywords:Quarkonium, heavy hybrids, exotic states, Born-Oppenheimer approximation, effective field theories
In order to understand the nature of the XYZ particles, theoretical predictions of the various XYZ decay modes are essential. In this work, we focus on the semi-inclusive decay of heavy quarkonium hybrids into traditional quarkonium in the Born-Oppenheimer EFT (BOEFT) framework. We find that our numerical results of the decay rates are different from the previous studies. We also develop a systematic framework in which the theoretical uncertainty can be systematically improved.
