Abstract

The observation of \ensuremathπ₁(1600)\ensuremath→\ensuremathπ\ensuremathρ is shown in the flux-tube model to be compatible with this state being a hybrid meson with branching ratio to this channel \ensuremath∼30%. The \ensuremathπ\ensuremathρ widths of other hybrids are related by rather general arguments. These results enable cross sections for photoproduction of hybrids to be predicted.
