Finite Temperature Quark Confinement
Confinement may be more easily demonstrated at finite temperature using the Polyakov loop than at zero temperature using the Wilson loop. A natural mechanism for confinement can arise via the coupling of the adjoint Polyakov loop to F 2 μν . We demonstrate this mechanism with a one-loop calculation of the effective potential for SU(2) gluons in a background field consisting of a non-zero color ...
متن کاملFinite Temperature Quark Confinement via Chromomagnetic Fields
A natural mechanism for finite temperature quark confinement arises via the coupling of the adjoint Polyakov loop to the chromomagnetic field. Lattice simulations and analytical results both support this hypothesis. Finite temperature SU(3) lattice simulations show that a large external coupling to the chromomagnetic field restores confinement at temperatures above the normal deconfining temper...
متن کاملLaztice Models of Quark Confinement at High Temperature
We consider the behavior of lattice models of quark confinement at high temperature. We find that confinement is strictly a low temperature phenomenon. At high temperatures a transition to a plasma-like phase occurs, In this phase free gluons form a plasma which Debye screens the quarks. . (Submitted to Phys. Rev. D. ) *Work supported in part by the Department of Energy.
متن کاملHeavy Quark Interactions in Finite Temperature QCD
We study the free energy of a heavy quark-antiquark pair in a thermal medium. We constuct a simple ansatz for the free energy for two quark flavors motivated by the Debye-Hückel theory of screening. PACS. 11.15.Ha, 12.38.Mh, 25.75.Nq
متن کاملOn Quark Confinement
A sufficient condition for the confinement of quarks is presented. Quarks are shown to be unobservable. Colour singlets are however, observables. The results of deep inelastic scattering are discussed. We argue that QCD does not exhibit a deconfining transition.
