Charge Exchange Reactions in the Peripheral Orbit Model

概要

論文の詳細を見る
In our previous paper we have proposed the peripheral orbit model by introducing a peripheral Regge trajectory in the direct channel. The radius an absorptivity of the orbit are related to Reα and Imα, respectively. The width of the orbit is introduced through the factor e(J, s) (O[exp(-MJ/p)] as ReJ→∞) and Imα. In this article the model is applied to exotic reactions into which no peripheral Regge trajectory can be introduced. The exotic forward reaction amplitudes are defined from their u-channel reaction amplitudes through analytic continuation. The imaginary parts of the exotic reaction amplitudes are shown to have non-peripheral components due to the analytic continuation of the factor e(J, s). The model is applied to π^-p→π^0n, π^-p→ηn, K^+n→K^0p and K^-p→K^^-^0n.
