Bound states from Regge trajectories in a scalar model

The calculation of bound state properties using renormalization group techn iques to compute the corresponding Regge trajectories is presented. In part icular, we investigate the bound states in different charge sectors of a sc alar theory with interaction phi (dagger)phi chi. The resulting bound state spectrum is surprisingly rich. Where possible we compare and contrast with known results of the Bethe-Salpeter equation in the ladder approximation a nd, in the nonrelativistic limit, with the corresponding Schrodinger equati on.
