Feynman rules for effective Regge action

Starting from the gauge invariant effective action in the quasi-multi-Regge kinematics (QMRK), we obtain the effective reggeized gluon (R) -- particle (P) vertices of the following types: \(RPP\), \(RRP\), \(RRPP\), \(RPPP\), \(RRPPP\), and \(RPPPP\), where the on-mass-shell particles are gluons, or...

Zusammenfassung:Starting from the gauge invariant effective action in the quasi-multi-Regge kinematics (QMRK), we obtain the effective reggeized gluon (R) -- particle (P) vertices of the following types: \(RPP\), \(RRP\), \(RRPP\), \(RPPP\), \(RRPPP\), and \(RPPPP\), where the on-mass-shell particles are gluons, or sets of gluons with small invariant masses. The explicit expressions satisfying the Bose-symmetry and gauge invariance conditions are obtained. As a comment to the Feynman rules for derivation of the amplitudes in terms of effective vertices we present a ``vocabulary'' for practitioners.
