Lattice QCD calculation of the B-(s) -> D-(s)* lv form factors at zero recoil and implications for vertical bar V-cb vertical bar

Harrison, Judd; Davies, Christine TH; Wingate, Matthew Bowen; Collaboration, HPQCD (PHYSICAL REVIEW D, 2018-03-09)

© 2018 authors. We present results of a lattice QCD calculation of B→D∗ and Bs→Ds∗ axial vector matrix elements with both states at rest. These zero recoil matrix elements provide the normalization necessary to infer a ...
The Hindered M1 Radiative Decay Υ(2S) → η_b(1S)γ from Lattice NRQCD

Hughes, Ciaran; Dowdall, Rachel J; Davies, Christine TH; Horgan, Ronald Raymond; von, Hippel Georg; Wingate, Matthew Bowen (APSPhysical Review D, 2015-11-03)

We present a calculation of the hindered M1 Υ(2S) → η_b(1S)γ decay rate using lattice nonrelativistic QCD. The calculation includes spin-dependent relativistic corrections to the NRQCD action through O(v⁶ ) in the quark’s ...
