Effective action for the Regge processes in QCD and in gravity

It is known, that the Gribov approach to the hadron-hadron high energy scattering is based on an effective field theory for the Pomeron interactions. The gluons and gravitons are reggeized and therefore it is natural to reformulate QCD and gravity at high energies in terms of the reggeons and their interactions. We review the basic ideas of the BFKL approach in QCD and in supersymmetric gauge models and present it in the form of the gauge-invariant effective theory for the reggeized gluon interactions. A similar generally covariant action for the reggeized gravitons is formulated in terms of effective currents satisfying the Hamilton-Jacobi equation. Its supersymmetric generalization is discussed.
