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.
