Non-perturbatively Improved Heavy-Light Mesons : Masses and Decay Constants
We present a study of the heavy-light spectrum and of the Dand B-meson decay constants. The results were obtained in the quenched approximation, by using the nonperturbatively improved Clover lattice action at β = 6.2, with a sample of 100 configurations, on a 243 × 64 lattice. After a careful analysis of the systematic errors present in the extraction of the physical results, by assuming quite...
متن کاملMasses and Decay Constants of Heavy-light Mesons Using the Multistate Smearing Technique
We present results for fB and masses of low-lying heavy-light mesons. Calculations were performed in the quenched approximation using multistate smearing functions generated from a spinless relativistic quark model Hamiltonian. Beta values range from 5.7 to 6.3, and light quark masses corresponding to pion masses as low as 300 MeV are computed at each value. We use the 1P{1S charmonium splittin...
متن کاملDecay constants of P- and D-wave heavy-light mesons.
We investigate decay constants of P and D-wave heavy-light mesons within the mock-meson approach. Numerical estimates are obtained using the relativistic quark model. We also comment on recent calculations of heavy-light pseudo-scalar and vector decay constants. Typeset using REVTEX
متن کاملLight meson masses and decay constants in 2 + 1 flavour domain wall QCD
We present results for light meson masses and psedoscalar meson decay constants in 2+1 flavour domain wall QCD with the DBW2 and Iwasaki gauge actions, using lattices with linear sizes in the range 1.6 to 2.2fm and u and d quark masses as low as one quarter of the strange quark mass. All data were generated on the QCDOC machines at the University of Edinburgh and Brookhaven National Laboratory....
متن کاملDecay Constants of Charged Pseudo - Scalar Mesons
Introduction. Charged mesons formed from a quark and an anti-quark can decay to a charged lepton and a neutrino when these objects annihilate via a virtual W boson [1]. Fig. 1 illustrates this process for the purely leptonic decay of a D + meson.
