Step Scaling with off-shell renormalisation
R. Arthur, P. A. Boyle
We make use of twisted boundary conditions for off-shell Rome-Southampton renormalisation. This allows to define the vertex function precisely, at a fixed physical momentum that ne…
Continuum Limit Physics from 2+1 Flavor Domain Wall QCD
Y. Aoki, R. Arthur, T. Blum +23
We present physical results obtained from simulations using 2+1 flavors of domain wall quarks and the Iwasaki gauge action at two values of the lattice spacing , (=\,1.7…
Domain Wall QCD with Near-Physical Pions
RBC Collaboration, UKQCD Collaboration, R. Arthur +16
We present physical results for a variety of light hadronic quantities obtained via a combined analysis of three 2+1 flavour domain wall fermion ensemble sets. For two of our ensem…
Light Meson Distribution Amplitudes
R. Arthur, P. A. Boyle, D. Brömmel +7
We calculated the first two moments of the light-cone distribution amplitudes for the pseudoscalar mesons ( and ) and the longitudinally polarised vector mesons (, …
A note on Rome-Southampton Renormalization with Smeared Gauge Fields
R. Arthur, P. A. Boyle, S. Hashimoto +1
We have calculated continuum limit step scaling functions of bilinear and four-fermion operators renormalized in a Rome-Southampton scheme using various smearing prescriptions for…
Continuum Limit of from 2+1 Flavor Domain Wall QCD
Y. Aoki, R. Arthur, T. Blum +17
We determine the neutral kaon mixing matrix element in the continuum limit with 2+1 flavors of domain wall fermions, using the Iwasaki gauge action at two different lattice s…
Lattice Results for Low Moments of Light Meson Distribution Amplitudes
R. Arthur, P. A. Boyle, D. Brömmel +5
As part of the UKQCD and RBC collaborations' N_f=2+1 domain-wall fermion phenomenology programme, we calculate the first two moments of the light-cone distribution amplitudes of th…
Selection Principles for Gaia
R. Arthur, A. Nicholson
The Gaia hypothesis considers the life-environment coupled system as a single entity that acts to regulate and maintain habitable conditions on Earth. In this paper we discuss thre…
Opening the Rome-Southampton window for operator mixing matrices
R. Arthur, P. A. Boyle, N. Garron +2
We show that the running of operators which mix under renormalization can be computed fully non-perturbatively as a product of continuum step scaling matrices. These step scaling m…
Scattering lengths in SU(2) gauge theory with two fundamental fermions
R. Arthur, V. Drach, M. Hansen +3
We investigate non perturbatively scattering properties of Goldstone Bosons in an SU(2) gauge theory with two Wilson fermions in the fundamental representation. Such a theory can b…
