Abstract
The high-energy behaviour in a multi-channel system is investigated in the framework of collinear asymptotic dynamics for massive particles. We consider the most general trilinear coupling of N different scalar fields. We find Regge behaviour and obtain closed expressions for the Regge trajectories and couplings. The results are corraborated in the multi-channel Bethe-Salpeter approach. The scattering processes dominated by single Regge trajectories are explicitly given.
