Numerical simulation of lattice-regulated QCD has become an important source of
information about strong interactions. In the last few years there has been an explosion of …

We calculate the neutral kaon mixing parameter BK in unquenched lattice QCD using
asqtad-improved staggered sea quarks and domain-wall valence quarks. We use the “2+ 1” …

We present results for the kaon mixing parameter BK calculated using HYP (hypercubic fat
link)-smeared improved staggered fermions on the asqtad lattices generated by the MILC …

We review recent developments in lattice QCD. We first give an overview of its formalism,
and then discuss lattice discretizations of fermions. We then turn to a description of the …

We perform a dynamical lattice computation of the Isgur-Wise functions τ 1/2 and τ 3/2 at
zero recoil. We consider three different light quark masses corresponding to 300 MeV≲ m …

We calculate the kaon B parameter, BK, to next-to-leading order in staggered chiral
perturbation theory. We find expressions for partially quenched QCD with three sea quarks …

One-loop matching of heavy-light currents is carried out for a highly improved lattice action,
including the effects of mixings with dimension 4 O (1/M) and O (a) operators. We use the …

Models of new physics induce KK¯ mixing operators having Dirac structures other than
the<? format?>“left-left” form of the standard model. We calculate the functional form of the …

We apply nonperturbative renormalization to bilinears composed of improved staggered
fermions.<? format?> We explain how to generalize the method to staggered fermions in a …

We calculate the kaon B-parameter, BK, in chiral perturbation theory for a partially
quenched, mixed-action theory with Ginsparg-Wilson valence quarks and staggered sea …
