Charm physics with highly improved staggered quarks
C. T. H. Davies, E. Follana, K. Hornbostel +5
We use a relativistic highly improved staggered quark action to discretize charm quarks on the lattice. We calculate the masses and the dispersion relation for heavy-heavy and heav…
Highly Improved Staggered Quarks on the Lattice, with Applications to Charm Physics
E. Follana, Q. Mason, C. Davies +5
We use perturbative Symanzik improvement to create a new staggered-quark action (HISQ) that has greatly reduced one-loop taste-exchange errors, no tree-level order a^2 errors, and…
High-precision determination of the light-quark masses from realistic lattice QCD
Quentin Mason, Howard D. Trottier, Ron Horgan +2
Three-flavor lattice QCD simulations and two-loop perturbation theory are used to make the most precise determination to date of the strange-, up-, and down-quark masses, , $m…
High Precision Fundamental Constants using Lattice Perturbation Theory
Quentin Mason, Howard Trottier, Ron Horgan
The HPQCD collaboration has a program for determining the fundamental constants of the Standard Model Lagrangian from lattice QCD. The most accurate method of doing this uses the n…
The Low-Lying Dirac Spectrum of Staggered Quarks
E. Follana, A. Hart, C. T. H. Davies +1
We investigate and clarify the role of topology and the issues surrounding the epsilon regime for staggered quarks. We study unimproved and improved staggered quark Dirac operators…
Accurate Determinations of from Realistic Lattice QCD
Q. Mason, H. D. Trottier, C. T. H. Davies +5
We obtain a new value for the QCD coupling constant by combining lattice QCD simulations with experimental data for hadron masses. Our lattice analysis is the first to: 1) include…
