Abstract
|
|
|
|
| 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: R P P, R R P, 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. (c) 2005 Elsevier B.V. All rights reserved. |
