Extended Geometric Scaling from Generalized Traveling Waves

Robi Peschanski

We define a mapping of the QCD Balitsky-Kovchegov equation in the diffusive approximation with noise and a generalized coupling allowing a common treatment of the fixed and running…

Jet quenching in the strongly-interacting quark-gluon plasma

C. Marquet, T. Renk

We propose a hybrid model for medium-induced parton energy loss, in which the hard scales in the process are treated perturbatively, while the soft scales which involve strong coup…

Energy loss and thermalization of heavy quarks in a strongly-coupled plasma

C. Marquet, G. Beuf, B. -W. Xiao

Using the AdS/CFT correspondence, we compute the medium-induced energy loss of a decelerating heavy quark moving through a strongly-coupled supersymmetric Yang Mills plasma. In the…

Long range rapidity correlations and the ridge in A+A collisions

Francois Gelis, Tuomas Lappi, Raju Venugopalan

We discuss results for n-gluon correlations that form the basis of the Glasma flux tube picture of early times in heavy ion collisions. Our formalism is valid to all orders in pert…
