Plaquette expectation value and lattice free energy of three - dimensional SU ( N c ) gauge theory

چکیده
We use high precision lattice simulations to calculate the plaquette expectation value in three-dimensional SU(Nc) gauge theory for Nc = 2, 3, 4, 5, 8. Using these results, we study the Nc-dependence of the first non-perturbative coefficient in the weak-coupling expansion of hot QCD. We demonstrate that, in the limit of large Nc, the functional form of the plaquette expectation value with ultraviolet divergences subtracted is 15.9(2) − 44(2)/N c .

Critical correlators of three-dimensional gauge theories at finite temperature: exact results from universality
According to the Svetitsky-Yaffe conjecture, a three-dimensional gauge theory undergoing a continuous deconfinement transition is in the same universality class as a two-dimensional statistical model with order parameter taking values in the center of the gauge group. This allows us to use conformal field theory techniques to evaluate exactly various correlation functions at the critical point....
متن کاملPlaquette expectation value and gluon condensate in three dimensions
In three dimensions, the gluon condensate of pure SU(3) gauge theory has ultraviolet divergences up to 4-loop level only. By subtracting the corresponding terms from lattice measurements of the plaquette expectation value and extrapolating to the continuum limit, we extract the finite part of the gluon condensate in lattice regularization. Through a change of regularization scheme to MS and (in...
متن کاملThe Three - Loop Lattice Free Energy
We calculate the free energy of SU(N) gauge theories on the lattice, to three loops. Our result, combined with Monte Carlo data for the average plaquette, gives a more precise estimate of the gluonic condensate.
متن کاملThe leading non-perturbative coefficient in the weak-coupling expansion of hot QCD pressure
Using Numerical Stochastic Perturbation Theory within three-dimensional pure SU(3) gauge theory, we estimate the last unknown renormalization constant that is needed for converting the vacuum energy density of this model from lattice regularization to the MS scheme. Making use of a previous nonperturbative lattice measurement of the plaquette expectation value in three dimensions, this allows u...
متن کاملVortex solutions in SU(N ) adjoint Higgs theories
A relationship between vortex solutions in SU(N) gauge theories with two or more adjoint representation Higgs bosons and thick vortices of Center Vortex Theory is shown to exist. There is a similar relationship between monopole solutions of SU(N) gauge theories with a single adjoint representation Higgs boson and monopoles in Abelian Projection. New vortex solutions, relevant in central gauge f...
