Regge Poles in QCD | | A.B.Kaidalov
; | | Date: |
1 Mar 2001 | | Subject: | hep-ph | | Abstract: | Basic properties of Regge poles are reviewed. Regge poles are considered from both t-channel and s-channel points of view. The main part of the review is devoted to the Regge poles in QCD. The method of the Wilson-loop path integral is used to calculate trajectories of Regge poles for $q-ar q$ and gluonic states. The problem of the Pomeron in QCD is discussed in details. It is shown how to use the 1/N-expansion for classification of reggeon diagrams in QCD. The role of Regge cuts in reggeon theory is discussed and their importance for high-energy phenomenology is emphasized. Models based on the reggeon calculus, 1/N-expansion in QCD and string picture of interactions at large distances are reviewed and are applied to a broad class of phenomena in strong interactions. It is shown how to apply the reggeon approach to small-x physics in deep inelastic scattering. | | Source: | arXiv, hep-ph/0103011 | | Services: | Forum | Review | PDF | Favorites | |
