Reggeized gluon states in Quantum Chromodynamics
Jan Kotanski
Abstract
The reggeized gluon states, which are also called Reggeons, appear in the scattering amplitude of hadrons in Regge limit. The wave-function of Reggeons satisfy the BKP equation, which in multi-colour limit of Quantum Chromodynamics is equivalent to the Schrodinger equation of the XXX Heisenberg SL(2,C) spin chain model. In this work we solve the BKP equation, show the spectrum of the energy and other integrals of motion for a number of Reggeons N=2,...,8. Moreover, we consider deep inelastic scattering where due to the reggeized gluons states we are able to calculate anomalous dimensions and corresponding to their twists.
