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…
High Precision determination of the pi, K, D and D_s decay constants from lattice QCD
E. Follana, C. T. H. Davies, G. P. Lepage +1
We determine and decay constants from lattice QCD with 2% errors, 4 times better than experiment and previous theory: = 241(3) MeV, = 207(4) MeV and $f_{D…
Partially Quenched Chiral Perturbation Theory and a Massless Up Quark: A Lattice Calculation of the Light-Quark-Mass Ratio
Daniel R. Nelson
The nontrivial topological structure of the QCD gauge vacuum generates a CP breaking term in the QCD Lagrangian. However, measurements of the neutron electric dipole moment have de…
Progress report on the staggered epsilon'/epsilon project
T. Bhattacharya, G. T. Fleming, G. Kilcup +3
We report on progress and future plans for calculating kaon weak matrix elements for epsilon'/epsilon using staggered fermions.
