Mass anomalous dimension in SU(2) with two adjoint fermions

- Francis Bursa, L. Debbio, L. Keegan, C. Pica, Thomas Pickup
- Physics
- 23 October 2009

We study SU(2) lattice gauge theory with two flavours of Dirac fermions in the adjoint representation. We measure the running of the coupling in the Schrodinger Functional (SF) scheme and find it is… Expand

Running of the coupling and quark mass in SU(2) with two adjoint fermions

- Francis Bursa, L. Debbio, L. Keegan, C. Pica, Thomas Pickup
- Physics
- 14 October 2009

We simulate SU(2) gauge theory with two massless Dirac fermions in the adjoint representation. We calculate the running of the Schroedinger Functional coupling and the renormalised quark mass over a… Expand

The $SU(\infty)$ twisted gradient flow running coupling

- M. P'erez, A. Gonz'alez-Arroyo, L. Keegan, M. Okawa
- Physics
- 2 December 2014

We measure the running of the $SU(\infty)$ 't Hooft coupling by performing a step scaling analysis of the Twisted Eguchi-Kawai (TEK) model, the SU($N$) gauge theory on a single site lattice with… Expand

RHMC with Block Solvers and Multiple Pseudofermions

- P. D. Forcrand, L. Keegan
- Physics
- 6 August 2018

The dominant cost of most lattice QCD simulations is the inversion of the Dirac operator required to calculate the force term in the RHMC update. One way to improve this situation is to use multiple… Expand

Mass Anomalous Dimension at large N

- L. Keegan
- Physics
- 26 October 2012

In this work we attempt to determine the mass anomalous dimension of the SU(N) gauge theory with two Dirac fermions in the adjoint representation, in the limit of large N. The method uses the mode… Expand
