Dips in Partial Wave Amplitudes from Final State Interactions

Abstract

We consider the dip-peak structures in the J=0 partial wave amplitudes for processes $\gamma \gamma \to W^{+}{W}^{-}\text{mbox}and\gamma \gamma ,gg\to t\overline{t}$ taking into account the corresponding Born term process and the rescattering process where the intermediate state is rescattered through the exchange of Higgs resonance state in the direct channel.
