摘要
<p>Using the AdS/CFT correspondence for strongly coupled gauge theories, we calculate thermalization of mesons caused by a time-dependent change of a baryon-number chemical potential. On the gravity side, the thermalization corresponds to a horizon formation on the probe flavor brane in the AdS throat. Since heavy-ion collisions are locally approximated by a sudden change of the baryon-number chemical potential, we discuss the implication of our results to RHIC and LHC experiments, to find a rough estimate of the rather rapid thermalization time-scale t(th) < 1 [fm/c]. We also discuss the universality of our analysis against varying gauge theories.</p>
