Quark 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 کاملChromo-hydrodynamic Approach to the Unstable Quark-gluon Plasma
We derive hydrodynamic-like equations that are applicable to short-time scale color phenomena in the quark-gluon plasma. The equations are solved in the linear response approximation, and the gluon polarization tensor is derived. As an application, we study the collective modes in a two-stream system and find plasma instabilities when the fluid velocity is larger than the speed of sound in the ...
متن کاملRadiative energy loss of high energy quarks in finite-size nuclear matter and quark-gluon plasma
The induced gluon radiation of a high energy quark in a finite-size QCD medium is studied. For a sufficiently energetic quark produced inside a medium we find the radiative energy loss ∆Eq ∝ L, where L is the distance passed by quark in the medium. It has a weak dependence on the initial quark energy Eq. The L 2 dependence turns to L as the quark energy decreases. Numerical calculations are per...
متن کاملOn the Energy Loss of High Energy Quarks in a Finite-size Quark-gluon Plasma
We study within the light-cone path integral approach the induced gluon emission from a fast quark passing through a finite-size QCD plasma. We show that the leading log approximation used in previous studies fails when the gluon formation length becomes of the order of the length of the medium traversed by the quark. Calculation of the energy loss beyond the leading log approximation gives the...
متن کاملRadiative Energy Loss of High Energy Quarks and Gluons in a Finite Volume Quark-gluon Plasma
The medium induced energy loss spectrum of a high energy quark or gluon traversing a hot QCD medium of finite volume is studied. We model the interaction by a simple picture of static scattering centres. The total induced energy loss is found to grow as L, where L is the extent of the medium. The solution of the energy loss problem is reduced to the solution of a Schrödingerlike equation whose ...
