Instabilities in an Anisotropically Expanding Quark-Gluon Plasma

Abstract:

Nonabelian plasma instabilities have been proposed as a possible mechanism for the fast apparent thermalization of the quark-gluon plasma and have been extensively studied in stationary anisotropic plasmas using the so-called hard-loop approximation. The generalization to the HEL (hard-expanding-loop) formalism allows the (numerical) calculation of the time evolution of gluonic mean fields in the more realistic dynamical case of anisotropic expansion.
