Causal Propagators for Algebraic Gauges

چکیده
Applying the principle of analytic extension for generalized funtions we derive causal propagators for algebraic non-covariant gauges. The so generated manifestly causal gluon propagator in the light-cone gauge is used to evaluate two one-loop Feynman integrals which appear in the computation of the three-gluon vertex correction. The result is in agreement with that obtained through the usual prescriptions. Classi cation: PACS. Nos. 11.15.Bt; 12.38.Bx ||||||||||||||||||||||With partial support of CNPq, Bras lia ?

متن کاملInfrared Propagators in MAG and Feynman gauge on the lattice
We propose to investigate infrared properties of gluon and ghost propagators related to the so-called Gribov-Zwanziger confinement scenario, originally formulated for Landau and Coulomb gauges, for other gauges as well. We present results of our investigation of SU(2) lattice gauge theory in the maximally Abelian gauge (MAG), focusing on the behavior of propagators in the off-diagonal (i.e. non...
متن کاملScreening in Hot SU(2) Gauge Theory and Propagators in 3d Adjoint Higgs model
We investigate the large distance behavior of the electric and magnetic propagators of hot SU(2) gauge theory in different gauges using lattice simulations of the full 4d theory and the effective, dimensionally reduced 3d theory. A comparison of the 3d and 4d data for the propagators suggests that dimensional reduction works surprisingly well down to temperatures T ∼ 2Tc. A detailed study of th...
متن کاملScreening Masses of Hot Su(2) Gauge Theory from the 3d Adjoint Higgs Model
We study the Landau gauge propagators of the lattice SU(2) 3d adjoint Higgs model, considered as an effective theory of high temperature 4d SU(2) gauge theory. From the long distance behaviour of the propagators we extract the screening masses. It is shown that the pole masses extracted from the propagators agree well with the screening masses obtained recently in finite temperature SU(2) theor...
متن کاملPropagators of Hot Su(2) Gauge Theory from 3d Adjoint Higgs Model *
We study propagators of the lattice 3d adjoint Higgs model, considered as an effective theory of 4d SU (2) gauge theory at high temperature. The propagators are calculated in so-called λ-gauges. From the long distance behaviour of the propagators we extract the screening masses. It is shown that the pole masses extracted from the propagators agree well with the screening masses obtained recentl...
