QCD Pressure at Two Loops in the Temporal Gauge
نویسندگان
چکیده
We apply the method of zeta functions, together with the nμ-prescription for the temporal gauge, to evaluate the thermodynamic pressure in QCD at finite temperature T . Working in the imaginary-time formalism and employing a special version of the unified-gauge prescription, we show that the pure-gauge contribution to the pressure at two loops is given by P gauge 2 = −(g/144)NcNgT 4, where Nc and Ng denote the number of colours and gluons, respectively. This result agrees with the value in the Feynman gauge. Permanent address: Department of Mathematics and Statistics, University of Guelph, Guelph, Ontario, N1G 2W1; E-mail: [email protected] 1

Anisotropic Lattices and Dynamical Fermions ∗
We report results from full QCD calculations with two flavors of dynamical staggered fermions on anisotropic lattices. The physical anisotropy as determined from spatial and temporal masses, their corresponding dispersion relations, and spatial and temporal Wilson loops is studied as a function of the bare gauge anisotropy and the bare velocity of light appearing in the Dirac operator. The anis...

The conventional weak-coupling expansion for thermodynamic quantities in hot field theories shows poor convergence unless the coupling constant is tiny. I discuss screened perturbation theory (SPT) which is a way of reorganizing the perturbative expansion for scalar theories and hard-thermal-loop perturbation theory (HTLPT), which is its generalization to gauge theories. I present results for t...

We explore the phase diagram of SU(2) Lattice Gauge Theory with dy-namical fermions in the temperature, mass, chemical potential space. We observe qualitative changes of the dependence of the particle density on µ and T , which is compatible with that expected of a gas of free massless quarks n ∝ µ 3 only for T ≃ T c. At the onset for thermodynamics the interquark potential flattens at large se...

To understand color confinement mechanism in QCD is absolutely necessary for us to analytically explain hadron physics starting from QCD [1,2]. The ’tHooft idea of abelian projection in which a partial gauge-fixing is done keeping the maximal abelian torus group unbroken is very interesting [3]. Then QCD can be regarded as a U(1) × U(1) abelian gauge theory with magnetic monopoles and electric ...
متن کاملDifficulties in inducing a gauge theory at large N.
It is argued that the recently proposed Kazakov-Migdal model of induced gauge theory, at large N , involves only the zero area Wilson loops that are effectively trees in the gauge action induced by the scalars. This retains only a constant part of the gauge action excluding plaquettes or anything like them and the gauge variables drop out. Address for correspondence. Email: [email protected]...
