Kurzfassung englisch:
The theory of the strong interaction - quantum chromodynamics - predicts
the creation of a Quark-Gluon Plasma in ultrarelativistic heavy ion
collisions. Experimental evidence suggests that this plasma thermalizes,
hence reaches thermal equilibrium, very soon after the collision.
The mechanism for the fast thermalization of the system is yet unknown.
Conventional methods like elastic scattering of two bodies cannot
account for this surprisingly strong collective behavior, therefore
one needs to examine new collective effects such as plasma instabilities.
We will review the effect of the chromo-Weibel instability, which
generates highly excited collective modes, in a hot plasma.
We find that there is rapid longitudinal thermalization of the plasma
even in the expanding case due to the non-linear mode couplings inherent
in the unstable evolution.
