Spectrum and decay matrix elements of B and D-mesons in lattice NRQCD
نویسنده
چکیده
We discuss recent results on the excitation spectra of B and D-mesons obtained in the framework of nonrelativistic lattice QCD in the quenched approximation. The results allow for the determination of the MS-mass of m b,MS (m b,MS ) = 4.34(7) GeV in O(α3s) in the perturbative matching. The determination of the decay constants fBs and fDs is discussed in detail. Results for the matrix elements of semi-leptonic B to D decays are shown. CLNS 00-1689 hep-ph/0009088

fB and the Heavy-light Spectrum from NRQCD
B physics is a subject of active research. The theoretical and experimental understanding of the B meson and b baryon spectrum is just beginning. Weak matrix elements of B mesons, e.g. fB, fBs , BB, and BBs are being studied to determine fundamental parameters of the Standard Model. This review summarizes the progress made in calculating the B spectrum and decay constants using the nonrelativis...
متن کاملHeavy - light spectrum and decay constant from NRQCD with two flavors of dynamical quarks ∗
The decay constant fB is being studied extensively on the lattice because of its importance for the determination of CKM matrix elements. The spectrum of excited B mesons and b baryons is being measured in present experiments, whereas there exist only few lattice results on this subject. In this article we report on our study of B mesons in two-flavor full QCD employing the NRQCD action for hea...
متن کاملThe charmed and bottom meson spectrum from lattice NRQCD
B (∗) s ) are well known experimentally, and thus provide a testing ground for the lattice method. In particular, they can be used to examine the convergence properties of the heavy quark expansion in nonrelativistic QCD (NRQCD),[1] which is the most economical lattice action available for heavy quark physics.[2] The spectrum of P-wave heavy-light mesons is not yet understood, experimentally no...
متن کاملMesonic decay constants in lattice NRQCD
Lattice NRQCD with leading finite lattice spacing errors removed is used to calculate decay constants of mesons made up of heavy quarks. Quenched simulations are done with a tadpole improved gauge action containing plaquette and six-link rectangular terms. The tadpole factor is estimated using the Landau link. For each of the three values of the coupling constant considered, quarkonia are calcu...
متن کاملQCD radiative corrections to the leptonic decay rate of the Bc meson.
The QCD radiative corrections to the leptonic decay rate of the B c meson are calculated using the formalism of nonrelativistic QCD (NRQCD) to separate short-distance and long-distance effects. The B c decay constant is factored into a sum of NRQCD matrix elements each multiplied by a short-distance coefficient. The short-distance coefficient for the leading matrix element is calculated to orde...
