Exact renormalization group offers new insights into multi-scale plasma physics
Progress in semi-analytic calculations of quark-gluon plasma thermodynamics
Abstract
This talk reviews progress in the (semi-) analytic calculations of the thermodynamics of the quark-gluon plasma. I shall explain how weak coupling techniques can allow us, through appropriate resummations, to deal with particular non perturbative aspects of the quark-gluon plasma. Then I shall show how the exact renormalization group may provide insight into the physics of this multi-scale system
