Improved Lattice QCD $B_{c} \to J / ψ$ Vector, Axial-Vector, and Tensor Form Factors

Judd Harrison

We present an update of HPQCD's lattice QCD determination of the $B_{c} \to J / ψ$ vector and axial-vector form factors, and provide new results for the tensor form factors. We use the…

Heavy-light meson decay constants and hyperfine splittings with the heavy-HISQ method

Kerr A. Miller, Judd Harrison, Christine T. H. Davies +1

We compute ratios between the vector and pseudoscalar, and tensor and vector decay constants, and between hyperfine splittings for $D_{(s)}^{(*)}$ and $B_{(s)}^{(*)}$ mesons. We us…

Lattice QCD matrix elements for the $B_{s}^{0} - B ˉ_{s}^{0}$ width difference beyond leading order

Christine T. H. Davies, Judd Harrison, G. Peter Lepage +3

Predicting the $B_{s}^{0} - B ˉ_{s}^{0}$ width difference $Δ Γ_{s}$ relies on the heavy quark expansion and on hadronic matrix elements of $Δ B = 2$ operators. We present the first lattice QCD…

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…
