Glueball masses and Regge trajectories for the QCD-inspired potential
arXiv:1206.7099 · doi:10.1140/epjc/s10052-012-2128-5
Abstract
Bound state of two massive constituent gluons is studied in the potential approach. Relativistic quasi-classical wave equation with the QCD-inspired scalar potential is solved by the quasi-classical method in the complex plane. Glueball masses are calculated with the help of the universal mass formula. The hadron Regge trajectories are given by the complex non-linear function in the whole region of the invariant variable . The Chew-Frautschi plot of the leading glueball trajectory, , has the properties of the t-channel Pomeron, which is dual to the glueball states in the s channel. The imaginary part of the Pomeron is also calculated.
