Coupled-Channels Model of Self-Consistent Regge Trajectories

Abstract

A model in which a vacuum $P$ and a meson $M$ Regge trajectory are present is studied in the framework of the multiperipheral bootstrap. Simultaneous self-consistency is imposed on the intercepts and slopes of both trajectories. In this model the $P$ slope tends to be larger than the $M$ slope, and if the $P$ intercept at $t=0\mathrm{}$ is close to 1, the $P$ exchange does not give rise to strong effects.
