Finite temperature formalism for non-Abelian gauge theories in the physical phase space.

We establish a new framework of finite temperature field theory for YangMills theories in the physical phase space eliminating all unphysical degrees of freedoms. Relating our method to the imaginary time formalism of James and Landshoff in temporal axial gauge, we calculate the two-loop pressure and provide a systematic and unique method to construct the additional vertices encountered in thei...

Increasing Potentials in Non-Abelian and Abelian Gauge Theories

An exact solution for an SU(2) Yang-Mills field coupled to a scalar field is given, which has potentials with a linear and a Coulomb part. This may have some physical importance since many phenomenological QCD studies assume a linear plus Coulomb potential. Usually the linear potential is motivated with lattice gauge theory arguments. Here the linear potential is an exact result of the field eq...

Gauge fixing and BRST formalism in non-Abelian gauge theories

In this Thesis we present a comprehensive study of perturbative and non-perturbative non-Abelian gauge theories in the light of gauge-fixing procedures, focusing our attention on the BRST formalism in Yang-Mills theory. We propose first a model to re-write the Faddeev-Popov quantisation method in terms of grouptheoretical techniques and then we give a possible way to solve the no-go theorem of ...

Basis Invariants in Non–Abelian Gauge Theories

A basis of Lorentz and gauge-invariant monomials in non-Abelian gauge theories with matter is described, applicable for the inverse mass expansion of effective actions. An algorithm to convert a arbitrarily given invariant expression into a linear combination of the basis elements is presented. The linear independence of the basis invariants is proven.
