The "forbidden" decays of hybrid mesons to πρ can be large
F. E. Close, J. J. Dudek
Abstract
The observation of π1(1600) πρ is shown in the flux-tube model to be compatible with this state being a hybrid meson with branching ratio to this channel 30%. The πρ widths of other hybrids are related by rather general arguments. These results enable cross sections for photoproduction of hybrids to be predicted.
