B Meson Decay Constants Using NRQCD
نویسنده
چکیده
Recent results for B meson decay constants with NRQCD b-quarks and clover light quarks are discussed. Perturbative matching factors through O(α/M) are now available and incorporated into the analyses. An O(α a) improvement term to the heavy-light axial current is identified and included. The slope of fP S √ MP S versus 1/MP S is significantly reduced by these corrections.

B Meson Decay Constants From NRQCD
We present quenched results for B meson decay constants using NRQCD b quarks and O(a) tadpole improved clover light quarks. For the first time, one-loop matching factors between lattice and continuum currents are incorporated through O(α/M) taking operator mixing fully into account. This includes an important O(α a) discretization correction to the heavy-light axial vector current. We find f B ...
متن کاملHeavy-Light Mesons with Quenched Lattice NRQCD: Results on Decay Constants
We present a quenched lattice calculation of heavy-light meson decay constants, using non-relativistic (NRQCD) heavy quarks in the mass region of the b quark and heavier, and clover-improved light quarks. The NRQCD Hamiltonian and the heavy-light current include the corrections at first order in the expansion in the inverse heavy quark mass. We study the dependence of the decay constants on the...
متن کاملB Decay Constants from NRQCD with Dynamical Fermions
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 quarks. We calculate the pseudoscalar and vector decay constants over a wide range in heavy quark mass and are able to perform a detailed analysis of heavy quark symmetry. We find consistency between the extrapolation of t...
متن کاملScaling and further tests of heavy meson decay constant determinations from nonrelativistic QCD
We present results for the B s meson decay constant f B s from simulations at three lattice spacings in the range a Ϫ1 ϭ1.1 to 2.6 GeV using NRQCD heavy quarks and clover light quarks in the quenched approximation. We study the scaling of this quantity and check the consistency between mesons decaying from rest and from a state with a nonzero spatial momentum. The cancellation of power law cont...
متن کاملB Physics with Nrqcd: a Quenched Study
We present results on the spectrum of B mesons and heavy baryons, using a non-relativistic formulation for the heavy and a clover action for the light quark. We also discuss B meson decay constants and their dependency upon the heavy meson mass.
