Update: Accurate Determinations of alpha_s from Realistic Lattice QCD

C. T. H. Davies, K. Hornbostel, I. D. Kendall +4

We use lattice QCD simulations, with MILC configurations (including vacuum polarization from u, d, and s quarks), to update our previous determinations of the QCD coupling constant…

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…

Four Fermion Operator Matching with NRQCD Heavy and AsqTad Light Quarks

Elvira Gamiz, Junko Shigemitsu, Howard Trottier

We present one-loop matching coefficients between continuum and lattice QCD for the heavy-light four-fermion operators relevant for neutral B meson mixing both within and beyond th…

Unquenching effects on the coefficients of the Lüscher-Weisz action

Zh. Hao, G. M. von Hippel, R. R. Horgan +2

The effects of unquenching on the perturbative improvement coefficients in the Symanzik action are computed within the framework of Lüscher-Weisz on-shell improvement. We find that…

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…

Mixing Parameters from Unquenched Lattice QCD

Emel Dalgic, Alan Gray, Elvira Gamiz +5

We determine hadronic matrix elements relevant for the mass and width differences, & in the meson system using fully unquenched lattice QCD. We…
