Heavy Hybrid Decays in a Constituent Gluon Model

Abstract

A constituent gluon model that is informed by recent lattice field theory is developed. The model is then used to compute hybrid strong decay widths, that can be useful for the GlueX collaboration at Jefferson Lab and the PANDA collaboration at FAIR. Commensurately, forthcoming data from GlueX and PANDA will test the model. Widths tend to be large except for those of the lightest hybrid $S$-wave multiplet. Selection rules, extensions, limitations, and applications are discussed.

arXiv commentA numerical error in the state normalization has been corrected. New table and reference added. Discussion updated. Affiliation and acknowledgements updated
