M(12) and Vector-Meson Production at High Energy

概要
- 論文の詳細を見る
The method used in a previous paper for discussion of the bump-behavior of the differential cross section near the forward direction is applied to the vector meson production. It is assumed that, for the forward amplitudes, M(12) is broken in such a way that at high energy the contributions from intermediate states with parity (-1)^<J+1> in the t channel are suppressed for some reason in comparison with those from the states with parity (-1)^J, J being the total angular mementum. M(12) is used only for the calculation of the ratios of the helicity amplitudes in the forward direction. Bump-behavior is expected for almost all vector meson production processes. The results are consistent with experiments.
