Phenomenological Treatment of theϱTrajectory

Abstract
A phenomenological method is applied to the ρ trajectory. It is argued that once the intercept is known, the method is expected to give reliable information about the trajectory in the region of interest for highenergy scattering. Solutions for different values of the intercept ranging from 0.3 to 0.8 are given. From certain general requirements the higher intercepts seem to be favored.
