"Multiplicities from black-hole formation in heavy-ion collisions"

Presented by Anastasios Taliotis, University of Crete

Friday, December 16, 2011, 2:00 pm — Small Seminar Room, Bldg. 510

The formation of trapped surfaces in the head-on collision of shock waves in conformal and non-conformal backgrounds is investigated. The backgrounds include all interesting conning and non-conning backgrounds that may be relevant for QCD. Several transverse proles of the shocks are investigated including distributions that fall-o as powers or exponentials. Dierent ways of cutting-o the UV contributions (that are expected to be perturbative in QCD) are explored. Under some plausible simplifying assumptions our estimates are converted into predictions for multiplicities for heavy-ion collisions at RHIC and LHC.
