Inclusive Hadronic Distributions Inside One Jet at High Energy Colliders at "Modified Leading Logarithmic Approximation" of Quantum Chromodynamics
Abstract
After demonstrating their general expressions valid at all x, double differential 1-particle inclusive distributions inside a quark and a gluon jet produced in a hard process, together with the inclusive k-transverse distributions, are calculated at small x in the Modified Leading Logarithmic Approximation (MLLA), as functions of the transverse momentum of the outgoing hadron. Results are compared with the Double Logarithmic Approximation (DLA) and a naive DLA-inspired evaluation; sizable corrections are exhibited which, associated with the requirement to stay in a perturbative regime, set the limits of the interval where our calculations can be trusted. We give predications for the LHC and Tevatron colliders.
