Quark-antiquark contribution to the BFKL kernel
arXiv:hep-ph/9711427 · doi:10.1016/S0370-2693(98)00044-6
Abstract
The quark-antiquark contribution to the BFKL kernel is calculated. Using the effective vertex for the $q\bar q$ pair production in the Reggeon-Reggeon collision we find this contribution by integrating the square of this vertex over relative transverse momenta and fractions of longitudinal momenta of produced particles.
