Four-particle solutions to Baxter equation of SL(2,C) Heisenberg spin magnet for integer conformal Lorentz spin and their normalizability
Abstract
Description
The four reggeized gluon states for non-vanishing Lorentz conformal spin $n_h$ are considered. To calculate their spectrum the Q-Baxter method is used. As a result we describe normalizable trajectory-like states, which form continuous spectrum, as well as discrete point-like solutions, which turn out to be non-normalizable. The point-like solutions exist due to symmetry of the Casimir operator where conformal weights $(h,\bar h) \to (h,1-\bar h)$.
