Thermodynamics of the QCD Plasma and the LargeN Limit
Abstract
The equilibrium thermodynamic properties of the SU(N) plasma are studied nonperturbatively in the largeN limit, via highprecision lattice simulations at temperatures from 0.8T{sub c} to 3.4T{sub c} (T{sub c} being the critical deconfinement temperature). Our results for SU(N) YangMills theories with N=3, 4, 5, 6, and 8 colors show a very mild dependence on N, supporting the idea that the QCD plasma could be described by models based on the largeN limit. We compare our data with various theoretical descriptions, including, in particular, the improved holographic QCD model proposed by Kiritsis and collaborators. We also comment on the relevance of an AdS/CFT description in a phenomenologically interesting temperature range where the system, while still strongly coupled, becomes approximately scale invariant. Finally, we extrapolate our results to the N>infinity limit.
