Nuclear Physics & RIKEN Theory Seminar

"AdS/CFT and Heavy Ion Collisions"

Presented by Edmond Iancu, Saclay, France

Friday, August 21, 2009, 2:00 pm — Small Seminar Room, Bldg. 510

After briefly recalling the experimental results at RHIC which support the picture of a strongly-coupled, deconfined QCD matter, I discuss applications of the string theory, via the AdS/CFT correspondence, to the study of such a form of matter. I emphasize some striking consequences of the strong-coupling scenario, like the absence of jets, the strong suppression of the parton distributions at large values of Bjorken-x, and a novel mechanism (the medium-induced parton branching) for the energy loss and the momentum broadening of a hard probe. I discuss a recent proposal for a lattice measurement which should clarify whether the quark-gluon plasma is effectively strongly-coupled or not in the temperature range of interest for RHIC and LHC.
