Query: The dimensionally reduced description of the high energy scattering and
  the effective action for the reggeized gluons   We discuss the high energy scattering of hadrons with the multi - Regge
kinematics. The effective $2D$ model for the interaction between the produced
hard gluons appears as a result of the dimensional reduction, which is similar
to the dimensional reduction $3+1$ D $\to 3$ D of the high temperature gauge
theory. It is demonstrated that being supplemented by the exchange by virtual
$3+1$ D gluons this $2D$ model gives rise to the hermitian version of the
effective action of Lipatov for the interaction between the ordinary and the
reggeized gluons.
