Derivative Expansions of the Exact Renormalisation Group and SU(N|N) Gauge Theory
John F. Tighe
We investigate the convergence of the derivative expansion of the exact renormalisation group, by using it to compute the beta function of scalar theory. We demonstrate that the de…
Gauge invariant regularisation via SU(N|N)
Stefano Arnone, Yuri A. Kubyshin, Tim R. Morris +1
We construct a gauge invariant regularisation scheme for pure SU(N) Yang-Mills theory in fixed dimension four or less (for N = infinity in all dimensions), with a physical cutoff s…
A gauge invariant regulator for the ERG
S. Arnone, Yu. A. Kubyshin, T. R. Morris +1
A gauge invariant regularisation for dealing with pure Yang-Mills theories within the exact renormalization group approach is proposed. It is based on the regularisation via covari…
Convergence of derivative expansions in scalar field theory
Tim R. Morris, John F. Tighe
The convergence of the derivative expansion of the exact renormalisation group is investigated via the computation of the beta function of massless scalar lambda phi^4 theory. The…
Gauge invariant regularisation in the ERG approach
S. Arnone, Yu. A. Kubyshin, T. R. Morris +1
A gauge invariant regularisation which can be used for non-perturbative treatment of Yang-Mills theories within the exact renormalization group approach is constructed. It consists…
