Twisted mass QCD and the FNAL heavy quark formalism
Craig McNeile
At tree level, I discuss modifying the FNAL heavy quark formalism to include a twisted mass term. I find that at maximal twist the so called KLM factor is independent of the heavy…
High-Precision Charm-Quark Mass and QCD Coupling from Current-Current Correlators in Lattice and Continuum QCD
I. Allison, E. Dalgic, C. T. H. Davies +12
We use lattice QCD simulations, with MILC gluon configurations and HISQ c-quark propagators, to make very precise determinations of moments of charm-quark pseudoscalar, vector and…
Pseudoscalar Flavor-Singlet Physics with Staggered Fermions
Eric B. Gregory, Alan Irving, Chris M. Richards +2
Accurately calculating the mass of flavor-singlet meson states from numerical lattice simulations is an important milestone for lattice QCD. Careful measurement of the full pseudos…
Methods for Pseudoscalar Flavour-Singlet Mesons with Staggered Fermions
Eric B. Gregory, Alan C. Irving, Chris M. Richards +1
We present the first 2+1 flavour lattice QCD calculations of pseudoscalar flavour-singlet propagators using improved staggered fermions. We explore the relevant techniques and disc…
The mass of the charm quark from unquenched lattice QCD at fixed lattice spacing
UKQCD Collaboration, A. Dougall, C. M. Maynard +1
We determine the mass of the charm quark () from lattice QCD with two flavors of dynamical quarks with a mass around the strange quark. We compare this to a determination in q…
Data storage issues in lattice QCD calculations
Craig McNeile
I describe some of the data management issues in lattice Quantum Chromodynamics calculations. I focus on the experience of the UKQCD collaboration. I describe an attempt to use a r…
