Gauge parameter dependence and gauge invariance in the Abelian Higgs model
We analyze gauge parameter dependence by using an algebraic method which relates the gauge parameter dependence of Green functions to an enlarged Slavnov-Taylor identity. In the course of the renormalization it turns out that gauge parameter dependence of physical parameters is already restricted at the level of Green functions. In a first step we consider the on-shell conditions which we find ...
متن کاملThermalisation of Gauge Bosons in the Abelian Higgs Model
The thermalisation rate for long wavelength fluctuations of the gauge field in the abelian Higgs model is calculated from the imaginary part of the self energy. The calculation is performed for both the symmetric and symmetry broken phase of the theory.

متن کاملEffect of the Scalar Condensate on the Linear Gauge Field Response in the Abelian Higgs Model
The effective equations of motion for low-frequency mean gauge fields in the Abelian Higgs model are investigated in the presence of a scalar condensate, near the high temperature equilibrium. We determine the current induced by an inhomogeneous background gauge field in the linear response approximation up to O(e), assuming adiabatic variation of the scalar fields. The physical degrees of free...
متن کاملStrings in the Abelian Higgs Model
We consider the monopole-antimonopole static potential in the confining phase of the Abelian Higgs model and in particular the corrections to the Coulomb-like potential at small distances r. By minimizing numerically the classical energy functional we observe a linear in r correction so that a string-tension term survives even at distances much smaller than apparent physical scales. We argue th...
