to semileptonic decay form factors from HISQ light and charm quarks
H. Na, C. T. H. Davies, E. Follana +2
We present a study of semileptonic decays on the lattice which employs the HISQ action for both the charm and the light quarks. We work with MILC unquenched…
B semileptonic decays with 2+1 dynamical quark flavors
Emel Gulez, Christine Davies, Alan Gray +3
We study semileptonic B decays, using MILC dynamical configurations with . NRQCD heavy and AsqTad light quark actions are used. We obtain the semileptonic form factors $f_…
Improvement and Taste Symmetry Breaking for Staggered Quarks
E. Follana, C. Davies, A. Hart +3
We compare several improved actions for staggered quarks. We study the effect of improvement on the taste changing interactions by calculating the splitting in the pion spectrum. W…
Further Improvements to Staggered Quarks
Eduardo Follana, Quentin Mason, Christine Davies +3
The improved staggered quark action has enabled breakthrough calculations of QCD with three light dynamical quarks. The largest remaining scaling violations come from "taste-…
