A Manifestly Gauge Invariant, Continuum Calculation of the SU(N) Yang-Mills two-loop beta function
Tim R. Morris, Oliver J. Rosten
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 t…

A Generalised Manifestly Gauge Invariant Exact Renormalisation Group for SU(N) Yang-Mills
Stefano Arnone, Tim R. Morris, Oliver J. Rosten
We take the manifestly gauge invariant exact renormalisation group previously used to compute the one-loop beta function in SU(N) Yang-Mills without gauge fixing, and generalise it…

Equivalence of Local Potential Approximations
Tim R. Morris
In recent papers it has been noted that the local potential approximation of the Legendre and Wilson-Polchinski flow equations give, within numerical error, identical results for a…
