Unitarity Corrections in High Energy QCD ∗
نویسنده
چکیده
The high energy limit of QCD is investigated in the generalized leading logarithmic approximation. We study unitarity corrections to the BFKL Pomeron containing t-channel states with up to six gluons. Special attention is given to the field theory structure of the corresponding multi–gluon amplitudes. We discuss the transition from two to six gluons in the t-channel.

Unitarity corrections from the high energy QCD effective action ∗
We investigate the derivation of reggeon transition vertices from Lipatov’s gauge invariant effective action for high energy processes in QCD. In particular we address the question of longitudinal integrations in order to reduce the vertices into the required purely transverse form. We explicitly derive the BFKL-kernel and verify vanishing of the 2-to-3 reggeon transition vertex. First results ...
متن کاملThe QCD dipole picture of small-x physics
The QCD dipole picture of BFKL dynamics provides an attractive theoretical approach to the study of the QCD (resummed) perturbative expansion of small-x physics and more generally to hard high-energy processes. We discuss applications to the phenomenology of proton structure functions in the HERA range and to the longstanding problem of unitarity corrections, and outline some specific predictio...
متن کاملThe Qcd S–matrix in the High–energy Limit
Let me consider the simplest scattering process that one can think of in perturbative QCD — the elastic scattering between two small color dipoles (or ‘onia’) at zero impact parameter, in the center–of–mass (COM) frame and at relative rapidity Y — and address a basic question: What is the high energy limit of the S–matrix for this collision ? On physical grounds, the answer seems quite clear: S...
متن کاملStatus of the NLO Corrections to the Photon Impact Factor
The total cross section for the scattering of two highly virtual photons, having virtualities Q1 and Q 2 2 at large centre-of-mass energy s (s ≫ Q 2 1, Q 2 2) is an excellent testing ground for the applicability of perturbative QCD in the Regge limit [1, 2]. If the energy is high enough to expect the validity of the Regge limit but not too high in order to suppress unitarity corrections we expe...
متن کاملWeak Gauge Boson Radiation in Parton Showers
The emission of W and Z gauge boson is included in a traditional QCD + QED shower. The unitarity of the shower algorithm links the real radiation of the weak gauge bosons to the negative weak virtual corrections. The shower evolution process leads to a competition between QCD, QED and weak radiation, and allows for W and Z boson production inside jets. Various effects on LHC physics are studied...
