About this Physics and Astronomy article
Heavy Hybrid Decays to Quarkonia by Nora Brambilla; Wai Kin Lai; Abhishek Mohapatra; Antonio Vairo is a Physics and Astronomy article available to read on EtoBox.
The decay rates of the XYZ exotics discovered in the heavy quarkonium sector are crucial observables for identifying the nature of these states. Based on the framework of nonrelativistic effective field theories, we calculate the rates of semi-inclusive decays of heavy quarkonium hybrids into conventional heavy quarkonia. We compute them at leading and subleading power in the inverse of the heavy-quark mass, extending and updating previous results. We compare our predictions with experimental data of inclusive decay rates for candidates of heavy quarkonium hybrids.
