چکیده
The manifestly gauge invariant exact renormalisation group provides a framework for performing continuum computations in SU (N) Yang-Mills theory, without fixing the gauge. We use this formalism to compute the two-loop β function in a manifestly gauge invariant way, and without specifying the details of the regularisation scheme.

A Primer for Manifestly Gauge Invariant Computations in SU(N) Yang-Mills
Abstract. It has recently been determined that, within the framework of the Exact Renormalization Group, continuum computations can be performed to any loop order in SU(N) Yang-Mills theory without fixing the gauge or specifying the details of the regularization scheme. In this paper, we summarise and refine the powerful diagrammatic techniques which facilitate this procedure and illustrate the...
متن کاملManifestly Gauge Invariant QCD
Building on recent work in SU(N) Yang-Mills theory, we construct a manifestly gauge invariant exact renormalization group for QCD. A gauge invariant cutoff is constructed by embedding the physical gauge theory in a spontaneously broken SU(N |N) gauge theory, regularized by covariant higher derivatives. Intriguingly, the construction is most efficient if the number of flavours is a multiple of t...
متن کاملA Generalised, Manifestly Gauge Invariant Exact Renormalisation Group for SU(N) Yang-Mills
We take the manifestly gauge invariant exact renormalisation group previously used to compute the one-loop β function in SU(N) Yang-Mills without gauge fixing, and generalise it so that it can be renormalised straightforwardly at any loop order. The diagrammatic computational method is developed to cope with general group theory structures, and new methods are introduced to increase its power, ...

A closed expression of the Euclidean Wilson-loop functionals is derived for pure Yang-Mills continuum theories with gauge groups SU(N) and U(1) and space-time topologies R 1 R 1 and R 1 S 1. (For the U(1) theory, we also consider the S 1 S 1 topology.) The treatment is rigorous, manifestly gauge invariant, manifestly invariant under area preserving diieomorphisms and handles all (piecewise anal...

A closed expression of the Euclidean Wilson-loop functionals is derived for pure Yang-Mills continuum theories with gauge groups SU(N) and U(1) and spacetime topologies R × R and R × S1. (For the U(1) theory, we also consider the S1 ×S1 topology.)
