Search for Mesons Suggested by the Veneziano Model

Recent Regge-pole models have predicted the existence of particles of well-defined mass lying on daughter trajectories of such known particles as the ρ. A search for the coherent photoproduction of these mesons from carbon has been made. None was found. We conclude that in the mass range 1.0-1.8 GeV such mesons are coupled to the photon or the nucleus, at least two orders of magnitude more weakly than is the ρ.
