Description

The scattering of a baryon consisting of three massive quarks is investigated in the high energy limit of perturbative QCD. We derive the elastic impact factors for 2, 3 and 4 gluons, and study the energy evolution of the corresponding elastic scattering amplitudes. We find that the baryon couples to the BFKL Pomeron, the BKP odderon and a new BKP Pomeron state composed of three Reggeons. This new state is found to decay into two BFKL Pomerons via a new $3\to 4$ Reggeon transition vertex. Implications of these findings for the unitarization of high energy baryon scattering amplitudes are discussed.
