"Longitudinal Thermalization via the Chromo-Weibel Instability";
Vortrag: Second Norwegian Winter Workshop on QCD in Extreme Conditions, Trondheim (Norway); 13.12.2012 - 15.12.2012.

Non-Abelian plasma instabilities play a crucial role in the
non-equilibrium dynamics of a weakly coupled quark-gluon plasma.
Using the discretized hard loop framework we calculate the time evolution
of soft gluonic fields in a longitudinally free streaming background.
Extrapolating our results to energies probed in relativistic heavy-ion
collisions we find a pressure anisotropy that persists for a few fm/c.
However, the chromofields quickly develop a Boltzmann longitudinal energy
spectrum suggesting a kind of rapid longitudinal thermalization
of the quark gluon plasma despite begin momentum-space anisotropic.
