Improving the Kinetic Couplings in Lattice Non-Relativistic QCD

Christine T. H. Davies, Judd Harrison, Ciaran Hughes +3

We improve the non-relativistic QCD (NRQCD) action by comparing the dispersion relation to that of the continuum through $O (p^{6})$ in perturbation theory. The one-loop mat…

Rare $B$ decays using lattice QCD form factors

R. R. Horgan, Z. Liu, S. Meinel +1

In this write-up we review and update our recent lattice QCD calculation of $B \to K^{*}$ , $B_{s} \to ϕ$ , and $B_{s} \to K^{*}$ form factors [arXiv:1310.3722]. These unquenched calculation…

B-meson mixing from full lattice QCD with physical u, d, s and c quarks

R. J. Dowdall, C. T. H. Davies, R. R. Horgan +3

We present the first lattice QCD calculation of the $B_{s}$ and $B_{d}$ mixing parameters with physical light quark masses. We use MILC gluon field configurations that include $u$ , $d$ …

Matching lattice and continuum four-fermion operators with nonrelativistic QCD and highly improved staggered quarks

Christopher Monahan, Elvira Gamiz, Ron Horgan +1

We match continuum and lattice heavy-light four-fermion operators at one loop in perturbation theory. For the heavy quarks we use nonrelativistic QCD and for the massless light qua…

Calculation of $B^{0} \to K^{* 0} μ^{+} μ^{-}$ and $B_{s}^{0} \to ϕ μ^{+} μ^{-}$ observables using form factors from lattice QCD

Ronald R. Horgan, Zhaofeng Liu, Stefan Meinel +1

We calculate the differential branching fractions and angular distributions of the rare decays $B^{0} \to K^{* 0} μ^{+} μ^{-}$ and $B_{s}^{0} \to ϕ μ^{+} μ^{-}$ , using for the first time form fact…

Lattice QCD calculation of form factors describing the rare decays $B \to K^{*} ℓ^{+} ℓ^{-}$ and $B_{s} \to ϕ ℓ^{+} ℓ^{-}$

Ronald R. Horgan, Zhaofeng Liu, Stefan Meinel +1

The rare decays $B^{0} \to K^{* 0} μ^{+} μ^{-}$ and $B_{s} \to ϕ μ^{+} μ^{-}$ are now being observed with enough precision to test Standard Model predictions. A full understanding of these decay…
