Abstract:
The inclusive production of jets in the central region of rapidity is studied in -factorization at next-to-leading order (NLO) in QCD perturbation theory. Calculations are performed in the Regge limit making use of the NLO BFKL results. A jet cone definition is introduced and a proper phase--space separation into multi-Regge and quasi-multi-Regge kinematic regions is carried out. Two situations are discussed: scattering of highly virtual photons, which requires a symmetric energy scale to separate the impact factors from the gluon Green's function, and hadron-hadron collisions, where a non--symmetric scale choice is needed.- hadron hadron: inclusive reaction
- photon photon: inclusive reaction
- photon: off-shell
- jet: hadroproduction
- jet: photoproduction
- central region
- quantum chromodynamics: factorization
- transverse momentum: factorization
- perturbation theory: higher-order
