Direct photons: a nonequilibrium signal of the expanding quark-gluon plasma
Direct photon production from a longitudinally expanding quark-gluon plasma (QGP) at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies is studied with a real-time kinetic description that is consistently incorporated with hydrodynamics. Within Bjorken’s hydrodynamical model, energy nonconserving (anti)quark bremsstrahlung q(q̄) → q(q̄)γ and quark-antiquark annihilati...
متن کاملQuark energy loss in an expanding quark-gluon plasma
We study the quark energy loss in an expanding quark-gluon plasma. The expanding plasma produced in high energy AA-collision is described by Bjorken’s model. The dependence of the energy loss on the infrared cutoff for the radiated gluons, on the quark mass, and on the initial conditions of QCD plasma is investigated. Study of the induced gluon radiation from a fast quark in a quark-gluon plasm...
متن کاملTop-quark Production and QCD
We review theoretical calculations for top-quark production that include complete next-to-leading-order QCD corrections as well as higher-order soft-gluon corrections from threshold resummation. We discuss in detail the differences between various approaches that have appeared in the literature and review results for top-quark total cross sections and differential distributions at the Tevatron ...
متن کاملTop Quark Production Dynamics in Qcd *
A calculation of the total cross section for top quark production in hadronhadron collisions is presented based on an all-orders perturbative resummation of initial-state gluon radiative contributions to the basic quantum chromodynamics subprocesses. Principal-value resummation is used to evaluate all relevant large threshold contributions. In this method there are no arbitrary infrared cutoffs...
متن کاملHeavy Quark Production Processes in Qcd*
We discuss two novel QCD effecte which enhance the production of heavy quarks and supersymmetric hadrons beyond that conventionally expected from gluon fusion.
