2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/124714We review the AdS/CFT description of gauge theory plasmas for non-experts. We discuss the low shear viscosity, jet quenching, and J/psi-suppression, which are three major signatures for the quark-gluon plasma observed at RHIC experiments.12 pages, 12 figures, ReVTeX4; Based on invited talks presented at "Frontiers in the physics of quark-gluon plasma" (July 7-8 2006, RIKEN), "String theory and quantum field theory" (Sep. 12-16 2006, YITP), the Fall Meeting 2006 of the Physical Society of Japan (Sep. 20-22 2006, Nara Women's Univ.), "AdS/CFT and strongly coupled quark matter" (Nov. 21-22 2006, CCAST), YKIS2006 (Nov. 20-28 2006, YITP), and a string theory workshop at Rikkyo Univ.
