摘要：

The quark-antiquark contribution to the BFKL kernel is calculated. Using the effective vertex for the <q(q)over bar> 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.
