Semileptonic B Decays from an NRQCD/D234 Action
J. Shigemitsu, S. Collins, C. T. H. Davies +3
Semileptonic B decays are studied on quenched anisotropic lattices using Symanzik improved glue, NRQCD heavy quark and D234 light quark actions. We employ constrained fits to extra…
Semileptonic B Decays from an NRQCD/D234 Action
J. Shigemitsu, S. Collins, C. T. H. Davies +3
Semileptonic, B --> pi, l nubar, decays are studied on quenched anisotropic lattices using tree-level tadpole improved Symanzik glue, NRQCD heavy quark and D234 light quark actions…
Comparison Studies of Finite Momentum Correlators on Anisotropic and Isotropic Lattices
S. Collins, C. T. H. Davies, J. Hein +3
We study hadronic two- and three-point correlators relevant for heavy to light pseudoscalar meson semi-leptonic decays, using Symanzik improved glue, D234 light quark and NRQCD hea…
Decay Constants from NRQCD with Dynamical Fermions
S. Collins, U. M. Heller, J. Sloan +3
We present a lattice investigation of the heavy-light meson decay constants using Wilson light quarks and NRQCD heavy quarks, partially including the effects of dynamical sea quark…
Spectroscopy from NRQCD with Dynamical Fermions
S. Collins, U. M. Heller, J. Sloan +3
We present a lattice investigation, partially including the effects of dynamical quarks, of the heavy-light mesons using NRQCD for the heavy quark and the Wilson action for the lig…
Quenched Heavy-Light Decay Constants
UKQCD Collaboration
We present results for heavy-light decay constants, using both propagating quarks and the static approximation, in O(a)-improved, quenched lattice QCD. At beta=6.2 on a 24^3x48 lat…
