Gt. Condo et al., INELASTIC RHO(0) PHOTOPRODUCTION IN THE REACTION GAMMA-P -] RHO(0)PI(+)N, Physical review. D. Particles and fields, 49(5), 1994, pp. 2164-2168
Inelastic rho0 photoproduction in the reaction gammap --> rho0pi+n is
observed in the peripheral region \ t(gamma,rho0)' \ < 0.12 GeV2. The
data are consistent with the rho0 production being due to a double per
ipheral mechanism which conserves s-channel helicity. The pi+n produce
d in association with the rho0 is also consistent with the same mechan
ism, although there is a distortion of the expected angular distributi
ons in the pi+n mass region of 1.3-1.5 GeV/c2.
