چکیده
We present results of our quenched study of the B meson decay constant obtained with a parallel set of simulations with the Wilson and Clover actions at β=5.9, 6.1 and 6.3. Systematic errors associated with the large b-quark mass are analyzed within the Fermilab non-relativistic formalism. As our best estimate in the continuum limit we obtain fB=163±16 MeV and fB s =175±18 MeV with the Clover action.

Charm physics continues to pose difficulties for lattice QCD simulations. The systems are significantly relativistic [1,2] causing problems for the NRQCD approach, and have amQ ≃ O(1) causing significant discretisation effects in the heavy Wilson quark approach. We present the results of a simulation using the tadpole improved clover action and perform the analysis using the Fermilab [3] interp...

We present a high statistics study of the D-and B-meson decay constants. The results were obtained by using the Clover and Wilson lattice actions at β = 6.0 and 6.2.

Formulation of the heavy quark on the lattice, such as NRQCD[1] or the Fermilab approach with the Wilson-like relativistic quarks[2], requires perturbative matching with the continuum theory. Since the quark mass in the lattice unit cannot be neglected for these theories, the perturbative calculation is much more involved and have not developed as that for the massless case. We report the curre...

We present a quenched calculation of the form factors of the semileptonic weak decay B → πl¯ ν with O(1/mQ) NRQCD heavy quark and Wilson light quark on a 16 3 × 32 lattice at β = 5.8. The form factors are evaluated at six heavy quark masses, in the range of mQ ∼ 1.5 − 8 GeV. 1/mQ dependence of matrix elements are investigated and compared with HQET predictions. We observe clear signal for the f...

After a brief discussion of the promise and limitations of the lattice technique, I review lattice QCD results for several quantities of phenomenological interest. These are: matrix elements for heavy-to-light meson decays, leptonic decay constants f B and f D , the parameters B B and B K for neutral B and K meson mixing respectively, the strong coupling constant, light quark masses and the lig...
