Abstract

Direct evidence is presented for final- (and/or initial-) state interaction effects in 18 GeV/c $pd$ reactions involving inclusive $γ$ and $V^{0}$ production. This evidence is manifested as an excessive number of protonlike events as compared to the number of neutronlike events; an asymmetric distribution in center-of-mass longitudinal $V^{0}$ momentum for the protonlike events; and strong spectator-proton production-angle asymmetry correlated with high-momentum spectators.
