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 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…
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…
