title = "Properties of low-lying heavy-light mesons",
abstract = "We present preliminary results for fB and masses of low-lying heavy-light mesons in the static limit. Calculations were performed in the quenched approximation using multistate smearing functions generated from a Hamiltonian for a spinless relativistic quark. The 2S-1S and 1P-1S mass splitting are measured. Using the 1P-1S charmonium splitting to set the overall scale, the ground state decay constant fB, is 319 ± 11 (stat) MeV.",

note = "Funding Information: The efficacy of our smearing method is even greater at fl = 6.1 as can be seen by comparing Figs. 1 and 2 with Figs. 3 and 4 with the same physical volume. In addition to ground state properties, this method allows extraction of the properties of the lowest radially and orbitally excited states. Our results for these quantities are preliminary, and we expect more precise estimates to be obtained by further analysis. Further numerical studies are required to check the finite volume effects, determine the effect of using an improved action for the light quarks, and include additional light quark mass values at fl = 6.1 which will allow a better determination of the scaling behaviour of these properties of low-lying heavy-light states.
