DYNAMIC COLOR SCREENING IN A CLASSICAL QUARK PLASMA

Screening of a moving infinite color sheet source is examined in a qua rk plasma at finite temperature. The classical chromohydrodynamic equa tions for quarks are integrated, to obtain profiles for quark current density, which in turn are used to solve the SU(2) Yang-Mills equation s numerically. This provides. a classical but non-perturbative treatme nt for the screening of a moving source in quark plasma. The results s how two interesting features. We observe that if the test source is at rest the screening does not depend on the color dynamics and the beha vior is very similar to that in Coulomb plasma. When the test source i s moving with non-relativistic velocity the non-abelian features manif est themselves by weakening the screening and also by exhibiting an os cillatory profile with distance.
