Improved Vcs determination using precise lattice QCD form factors for D → Kℓν

Autor: Chakraborty, Bipasha, Parrott, W.G., Bouchard, C., Davies, C.T.H., Koponen, J., Lepage, G.P.

We provide a 0.8%-accurate determination of \ud V\ud c\ud s\ud from combining experimental results for the differential rate of \ud D\ud →\ud K\ud semileptonic decays with precise form factors that we determine from lattice QCD. This is the first t

Bottomonium precision tests from full lattice QCD: Hyperfine splitting, Υ leptonic width, and b quark contribution to e+e− → hadrons

Autor: Hatton, D., Davies, C.T.H., Koponen, J., Lepage, G.P., Lytle, A.T.

We calculate the mass difference between the \ud Υ\ud and \ud η\ud b\ud and the \ud Υ\ud leptonic width from lattice QCD using the Highly Improved Staggered Quark formalism for the \ud b\ud quark and including \ud u\ud , \ud d\ud , \ud s\ud and \u

Renormalization of the tensor current in lattice QCD and the \ud J\ud /\ud ψ\ud tensor decay constant

Autor: Hatton, D., Davies, C.T.H., Lepage, G.P., Lytle, A.T.

Lattice QCD calculations of form factors for rare Standard Model processes such as \ud B\ud →\ud K\ud ℓ\ud +\ud ℓ\ud −\ud use tensor currents that require renormalisation. These renormalisation factors, \ud Z\ud T\ud , have typically been cal

Charmonium properties from lattice \ud QCD\ud +\ud QED\ud : Hyperfine splitting, \ud J\ud /\ud ψ\ud leptonic width, charm quark mass, and \ud a\ud c\ud μ

Autor: Hatton, D., Davies, C.T.H., Galloway, B., Koponen, J., Lepage, G.P., Lytle, A.T.

We have performed the first \ud n\ud f\ud =\ud 2\ud +\ud 1\ud +\ud 1\ud lattice QCD computations of the properties (masses and decay constants) of ground-state charmonium mesons. Our calculation uses the HISQ action to generate quark-line connected t
