TL;DR
This paper studies the properties of the gluon plasma in SU(Nc) gauge theories, focusing on deconfinement transition, thermodynamics, and conformal behavior through lattice simulations of SU(4) and SU(6).
Contribution
It provides detailed lattice results for SU(4) and SU(6), analyzes the deconfinement transition scaling, and investigates the approach to conformality in the gluon plasma.
Findings
No evidence of a strongly coupled, conformal phase was found.
Continuum estimates of thermodynamic quantities were obtained.
The deconfinement transition point scales with lattice spacing.
Abstract
We investigate the deconfinement transition in SU(Nc) gauge theories, and properties of the deconfined phase. A detailed lattice study of SU(4) and SU(6) gauge theories are conducted, and finite volume and cutoff effects on thermodynamic observables are studied. The scaling of the deconfinement transition point with lattice spacing is used to calculate the scale, Lambda_MSbar. The continuum estimates of the thermodynamic quantities are used to study properties of the gluon plasma. In particular, the approach to conformal limit is studied. We do not find any evidence of a strongly coupled, conformal phase in these theories.
