چکیده

We show results for the B meson decay constant calculated both for B mesons at rest and those with non-zero momentum and using both the temporal and spatial components of the axial vector current. It is an important check of lattice systematic errors that all these determinations of fB should agree. We also describe how well different smearings for the B meson work at non-zero momentum-the optimal smearing has a narrow smearing on the b quark.

We review recent progress in calculating kaon spectrum, pseudoscalar meson decay constants, B K , ε ′ /ε, K → ππ matrix elements, kaon semileptonic form factors, and moments of kaon distribution amplitudes on the lattice. We also address the issue of how best to improve the staggered fermion formulation for the action and operators.
