We have studied the decays of the low-lying gluonic excitations of mesons (hybrids) predicted by a flux-tube model for chromodynamics. The probable reason for the absence to date of signals for such states is immediately explained: The lowest-lying hybrids decay preferentially to final states with one excited meson e. g. , B (1235), A₂ (1320), K^* (1420) K, (1300) pi,. . . rather than to two ground-state mesons (e. g. , , , K^*K,. . . ). We make specific predictions of decay channels which will contain J^PC exotic hybrid resonance signals and suggest some possibly fruitful production mechanisms.
