We have developed two methods for handling b quarks in lattice QCD. One uses NRQCD (now improved to include radiative corrections) and the other uses Highly Improved Staggered Quarks (HISQ), extrapolating to the b quark from lighter masses and using multiple lattice spacings to control discretisation errors. Comparison of results for the two different methods gives confidence in estimates of lattice QCD systematic errors, since they are very different in these two cases. Here we show results…

Quark Flavor Physics Review

I review the status of lattice-QCD calculations relevant to quark flavor physics. The recent availability of physical-mass ensembles with large physical volumes generated by a growing number of

Hyperfine splitting in the bottomonium system on the lattice and in the continuum

The latest experimental measurements of the hyperfine splitting $E_{\rm{hfs}}=M_{\Upsilon(1 S)}-M_{\eta_b(1 S)}$ done by the Belle collaboration and the perturbative and lattice QCD predictions show

Coulomb artifacts and bottomonium hyperfine splitting in lattice NRQCD

A bstractWe study the role of the lattice artifacts associated with the Coulomb binding effects in the analysis of the heavy quarkonium within lattice NRQCD. We find that a “na¨ıve” perturbative



Nonperturbative QCD Simulations with 2+1 Flavors of Improved Staggered Quarks

Dramatic progress has been made over the last decade in the numerical study of quantum chromodynamics (QCD) through the use of improved formulations of QCD on the lattice (improved actions), the

Vus from pi and K decay constants in full lattice QCD with physical u, d, s and c quarks

We determine the decay constants of the π and K mesons on gluon field configurations from the MILC Collaboration including u , d , s , and c quarks. We use three values of the lattice spacing and u/d

Highly improved staggered quarks on the lattice with applications to charm physics

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{sup 2} errors, and no tree-level

Lattice QCD ensembles with four flavors of highly improved staggered quarks

We present results from our simulations of quantum chromodynamics with four flavors of quarks: u, d, s, and c. These simulations are performed with a one-loop Symanzik improved gauge action and the

Bottomonium hyperfine splittings from lattice nonrelativistic QCD including radiative and relativistic corrections

We present a calculation of the hyperfine splittings in bottomonium using lattice nonrelativistic QCD. The calculation includes spin-dependent relativistic corrections through O(v6), radiative

Using new four-loop results for the heavy quark vacuum polarization and new data for bottom quark production in electron-positron annihilation, an update on the determination of charm- and

Precision tests of the J / ψ from full lattice QCD: Mass, leptonic width, and radiative decay rate to η c

We calculate the $J/\ensuremath{\psi}$ mass, leptonic width and radiative decay rate to $\ensuremath{\gamma}{\ensuremath{\eta}}_{c}$ from lattice QCD including $u$, $d$ and $s$ quarks in the sea for

Weak lensing observations of potentially X-ray underluminous galaxy clusters

Optically selected clusters of galaxies display a relation between their optical mass estimates and their X-ray luminosities LX that has a large scatter. A substantial fraction of optically selected
