Contribution
It introduces a novel effective Lagrangian tailored for multi-Regge kinematics in QCD, derived from the original QCD Lagrangian by mode elimination.
Findings
Provides a new framework for analyzing multi-Regge processes in QCD
Simplifies calculations by focusing on relevant modes in high-energy regimes
Lays groundwork for further theoretical and phenomenological studies
Abstract
We construct the effective Lagrangian describing QCD in the multi-Regge kinematics. It is obtained from the original QCD Lagrangian by eliminating modes of gluon and quark fields not appearing in this underlying kinematics.
