J. Bartels et Mg. Ryskin, ABSORPTIVE CORRECTIONS TO STRUCTURE FUNCTIONS AT SMALL-X, Zeitschrift fur Physik. C, Particles and fields, 60(4), 1993, pp. 751-756
The role of corrections due to the interactions between different bran
ches of parton (gluon) cascades is studied. It is shown that at HERA e
nergies these interactions increase the absorptive (two-Pomeron cut) c
ontributions by about 60 to 80% compared with the Gribov-Levin-Ryskin
equation.
