Analytic structure of the self-energy for massive gauge bosons at finite temperature.
We show that the one-loop self-energy at finite temperature has a unique limit as the external momentum pμ → 0 if the loop involves propagators with distinct masses. This naturally arises in theories involving particles with different masses as is demonstrated for a toy model of two scalars as well as in a U(1) Higgs theory. We show that, in spontaneously broken gauge theories, this observation...
متن کاملThe decay of unstable k-strings in SU(N) gauge theories at zero and finite temperature
Sources in higher representations of SU(N) gauge theory at T = 0 couple with apparently stable strings with tensions depending on the specific representation rather than on its N−ality. Similarly at the deconfining temperature these sources carry their own representation-dependent critical exponents. It is pointed out that in some instances one can evaluate exactly these exponents by fully expl...
متن کاملGauge-Invariant Renormalization Group at Finite Temperature
I describe an application of Wilson Renormalization group to the real time formalism of finite temperature field theory. The approach has two nice features: 1) the RG flow equations describe non-perturbatively the effect of thermal fluctuations only, and, 2) the flow is gauge invariant. I then describe the application of the method to the study of the gluon self-energy in SU(N), and present res...
متن کاملScreening of sources in higher representations of SU(N) gauge theories at zero and finite temperature
Completion of the Svetitsky-Yaffe conjecture in some (2+1) dimensional SU(N) gauge theories allows mapping Polyakov loops in higher representations of the gauge group into suitable conformal operators of the corresponding 2D CFT. As a consequence, the critical exponents of the correlators of these Polyakov loops are determined. The functional form of these correlators suggests a general Ansatz ...
متن کاملGapless color superconductivity at zero and at finite temperature
We present a detailed study of the recently proposed gapless color superconductivity in neutral two-flavor quark matter in β-equilibrium at zero as well as at finite temperature. We clarify the nature of the fermionic quasiparticles, and discuss the physical properties of this gapless phase of quark matter. The appearance of two “secondary” spin-1 condensates in the gapless ground state is poin...
