Effect of Color Screening on Heavy Quarkonia Regge Trajectories
M. M. Brisudova, L. Burakovsky, T. Goldman
Abstract
Using an unquenched lattice potential to calculate the spectrum of the bottomonium system, we demonstrate numerically that the effect of pair creation is to produce termination of hadronic Regge trajectories, in contrast to the Veneziano model and the vast majority of phenomenological generalizations. Termination of Regge trajectories may have significant experimental consequences.
