Non-abelian Plane-waves in the Quark-gluon Plasma
We present new, non-abelian, solutions to the equations of motion which describe the collective excitations of a quark-gluon plasma at high temperature. These solutions correspond to longitudinal and transverse plane-waves propagating through the plasma.

متن کاملQuark-Gluon Plasma Signatures
Aspects of quark-gluon plasma signatures that can be measured by CMS are discussed. First the initial conditions of the system from minijet production are introduced, including shadowing effects. Color screening of the Upsilon family is then presented, followed by energy loss effects on charm and bottom hadrons, high pT jets and global observables. ∗) This work was supported in part by the Dire...
متن کاملGluon Condensate and Parton Propagation in a Quark-gluon Plasma
Finite temperature QCD can be used to describe properties of a quark-gluon plasma (QGP) possibly created in the fireball of relativistic heavy ion collisions and in the early Universe. There are two different methods available, namely lattice QCD and perturbation theory. Lattice QCD is a non-perturbative method, which can be used at all temperatures above and below the phase transition. However...
متن کاملDynamical screening in a quark gluon plasma
We calculate the screening potential of a fast parton moving through a quark-gluon plasma in the framework of semi-classical transport theory. We found an anisotropic potential showing a minimum in the direction of the parton velocity. Possible consequences of this potential on binary states in a quark-gluon plasma are discussed. Screening of charges in a plasma is an important collective effec...
متن کاملJet conversions in a quark-gluon plasma
Quark and gluon jets traversing through a quark-gluon plasma not only lose their energies but also can undergo flavor conversions. The conversion rates via the elastic q(q̄)g → gq(q̄) and the inelastic qq̄ ↔ gg scatterings are evaluated in the lowest order in QCD. Including both jet energy loss and conversions in the expanding quark-gluon plasma produced in relativistic heavy ion collisions, we ha...
