چکیده
We present high-statistics results for neutral B-meson mixing and heavy-light-meson leptonic decays in the quenched approximation from tadpole-improved clover actions at β = 6.0 and β = 6.2. We consider quantities such as BBd(s) , fDd(s) , fBd(s) and the full ∆B = 2 matrix elements as well as the corresponding SU(3)-breaking ratios. These quantities are important for determining the CKM matrix element |Vtd|.

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...

We test the one-loop chiral perturbation theory formula on unquenched lattice data of pseudoscalar meson decay constants. The chiral extrapolation including the effect of the chiral logarithm is attempted and its uncertainty is discussed.

A lattice determination of the form factor and decay constants for the semileptonic decay of heavy pseudoscalar (PS) mesons at zero recoil is presented from which the soft pion relation is satisfied. Chiral extrapolation of the form factor is performed at constant q 2. Pole dominance is used to extrapolate the form factor in heavy quark mass. At the B mass, the form factor at zero recoil lies s...
