Abstract: | Screening of a moving infinite color sheet source is examined in a quark plasma at finite temperature. The classical chromohydrodynamic
equations for quarks are integrated, to obtain profiles for quark current density, which in turn are used to solve the SU(2)
Yang-Mills equations numerically. This provides a classical but non-perturbative treatment for the screening of a moving source
in quark plasma.
The results show two interesting features. We observe that if the test source is at rest the screening does not depend on
the color dynamics and the behavior is very similar to that in Coulomb plasma. When the test source is moving with non-relativistic
velocity the non-abelian features manifest themselves by weakening the screening and also by exhibiting an oscillatory profile
with distance. |
