abstract:In quantum physics, Regge theory is the study of the analytic properties of scattering as a function of angular momentum, where the angular momentum is not restricted to be an integer but is allowed to take any complex value. The nonrelativistic theory was developed by Tullio Regge in 1957.
In this paper, we take Reggetheoryas a basis to carry out a research on the possibilityofanalytic continuation. In combination withpotentialscattering, we discusssomequestionsinQCD.
