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 B Meson Decay Constant from Unquenched Lattice QCD
Alan Gray, Matthew Wingate, Christine T. H. Davies +5
We present determinations of the B meson decay constant f_B and of the ratio f_{B_s}/f_B using the MILC collaboration unquenched gauge configurations which include three flavors of…
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…
