Query: Gluon Pair Production in the Quasi-Multi-Regge Kinematics   To find the region of applicability of the leading log(1/x) approximation for
parton distributions in the small x region and to fix the argument of the QCD
running coupling it is necessary to know radiative corrections to the kernel of
the BFKL equation. The next-to-leading corrections to the BFKL kernel are
expressed in terms of the two-loop correction to the gluon Regge trajectory,
one-loop correction to the Reggeon-Reggeon-gluon vertex, and contributions from
two-gluon and quark-antiquark production in the quasi-multi-Regge kinematics.
We calculate differential and total cross sections of the two gluon production.
Differential cross section can be applied for description of two jet production
in the quasi-multi-Regge kinematics; the total cross section defines
corresponding correction to the BFKL kernel. To escape the infrared
divergencies we use dimensional regularization of the Feynman integrals.
