چکیده

We present preliminary results using NRQCD to describe heavy quarks on the MILC 2+1 flavour dynamical extra coarse ensemble. We calculate the spectra of low lying states in bottomonium to complement earlier results on the finer MILC ensembles. We then exploit the coarseness of the lattices to calculate charm propagators using NRQCD. These are used to examine the charmonium spectrum and to calclate the mass of the Bc using NRQCD. Finally we look breifly at the Bd and Bs systems using the imporoved staggered formalism to describe the light valence quarks.

Lattice simulations of B → π lν decays are problematic in the low q2 region when the pion has to have large momentum in the lattice frame for a B meson at rest or moving slowly. The movingNRQCD formalism provides a way around this by giving an accurate discretization of a b quark moving at arbitrary velocity v, and therefore a B meson moving at high momentum in the lattice frame. Here we show r...

Progress Calculating Decay Constants with NRQCD and AsqTad Actions

We combine a light AsqTad antiquark with a nonrelativistic heavy quark to compute the decay constants of heavy-light pseudoscalar mesons using the ensemble of 3-flavor gauge field configurations generated by the MILC collaboration. Preliminary results for fBs and fDs are given and status of the chiral extrapolation to fB is reported. We also touch upon results of the perturbative calculation wh...

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 NRQCD action for heavy quarks, the Asqtad improved naive action for light quarks, and the Symanzik improved glue action. These results are being used in recent heavy meson decay constant and semileptonic form facto...

Precision Scale Determination from the Upsilon Spectrum

We determine the radial excitation energy (2S-1S splitting)in the Upsilon spectrum using NRQCD b quarks on MILC configurations. We have statistical fitting errors of around 1% across a range of lattice spacing values using random wall sources, and this allows us to give improved determinations of the physical value of the heavy quark potential parameter r1. We also show improved results for the...

We give a progress report on studies of B s and B d mixing with valence NRQCD b quarks and asq-tad light quarks on the MILC configurations including the effect of 2+1 flavours of sea quarks. We explore methods for reducing statistical and systematic errors in the ratio ξ = f B s B B s / f B d B B d .
