Classification of four-Reggeon states in multi-colour QCD
Kotanski, Jan
Original · EN
N-Reggeized gluon states in Quantum Chromodynamics are described by BKP equation. In order to solve this equation for N>3 particles the Q-Baxter operator method is used. Spectrum of the integrals of motion of the system exhibits a complicated structure. In this work we consider the case with N=4 Reggeons where complicated relations between q₃-spectrum and q₄-spectrum are analysed. Moreover, corrections to WKB approximation for N=4 and q₃=0 are computed.
