Effective String Picture for Confining Gauge Theories at Finite Temperature
We study the “effective string picture” of confinement, deriving theoretical predictions for the interquark potential at finite temperature. At low temperatures, the leading string correction to the linear confining potential between a heavy quarkantiquark pair is the “Lüscher term”. Assuming a Nambu–Goto effective string action, subleading contributions can be worked out in an analytical way. ...
متن کاملEffective actions for finite temperature Lattice Gauge Theories
We consider a lattice gauge theory at finite temperature in (d+1) dimensions with the Wilson action and different couplings βt and βs for timelike and spacelike plaquettes. By using the character expansion and SchwingerDyson type equations we construct, order by order in βs, an effective action for the Polyakov loops which is exact to all orders in βt. As an example we construct the first non-t...
متن کاملThe Spatial String Tension in High Temperature Lattice Gauge Theories
We develop some techniques which allow an analytic evaluation of spacelike observables in high temperature lattice gauge theories. We show that such variables are described extremely well by dimensional reduction. In particular, by using results obtained in the context of “Induced QCD”, we evaluate the contributions to space-like observables coming from the Higgs sector of the dimensionally red...
متن کاملAn Effective Action for Finite Temperature Lattice Gauge Theories with Dynamical Fermions
Dynamical fermions induce via the fermion determinant a gauge-invariant effective action. In principle, this effective action can be added to the usual gauge action in simulations, reproducing the effects of closed fermion loops. Using lattice perturbation theory at finite temperature, we compute for staggered fermions the one-loop fermionic corrections to the spatial and temporal plaquette cou...
متن کاملSelf-consistently improved finite temperature effective potential for gauge theories.
The finite temperature effective potential of the Abelian Higgs Model is studied using the self-consistent composite operator method, which can be used to sum up the contributions of daisy and superdaisy diagrams. The effect of the momentum dependence of the effective masses is estimated by using a Rayleigh-Ritz variational approximation.
