B meson decays from moving-NRQCD on fine MILC lattices
C. T. H. Davies, G. P. Lepage, Kit Yan Wong
Lattice simulations of decays are problematic in the low region when the pion has to have large momentum in the lattice frame for a meson at rest or moving sl…
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…
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…
Unquenched determination of the kaon parameter B_K from improved staggered fermions
E. Gamiz, S. Collins, C. T. H. Davies +3
The use of improved staggered actions (HYP, Asqtad) has been proved to reduce the scaling corrections that affected previous calculations of B_K with unimproved (standard) staggere…
