Jet quenching at finite `t Hooft coupling and chemical potential from AdS/CFT | | Nestor Armesto

22 Jun 2006 | | Abstract: | Following the nonperturbative prescription for the jet quenching parameter recently proposed by Liu, Rajagopal and Wiedemann, we compute the first correction in the inverse `t Hooft coupling corresponding to string alpha’ corrections in the dual background. We also consider the introduction of a chemical potential for the U(1)^3 gauged R-symmetry. While the former mildly diminishes the jet quenching parameter -this suggesting a smooth interpolation between the strong coupling and perturbative results-, the latter generically increases its value. We comment on the extension of this setup to quarks of finite mass. | | Source: | arXiv, hep-ph/0606245 | | Services: | Forum | Review | PDF | Favorites | |
