B Meson Decay

The B-meson decay constant f B is calculated using the static approximation on the lattice. Our result for f B shows a large dependence on the size of smearing of operators used to create the B-meson. This result implies that one cannot extract the reliable physical value of f B from the lattice simulation with the static approximation.

B Mixing

The possibilities of B′ meson mixing is discussed. It is found that if fB′ is not much smaller than fπ, B's (or B'd) mixing is possible if |Vt′s Vt′b′/Vcb′| is large, but only for not too heavy b′ masses, e.g. below LEP I energies. The B'b meson will have large mixing for a broad range of parameters; however, it is hard to produce. The vector mesons (B′*) may exhibit mixing phenomena as well. A discussion of our present understanding of meson decay constants of a heavy-light system [Formula: see text] is given. Further efforts on this problem is needed, which will have an impact on our understanding of B mixing as well.

Good Agreement

The ratios of Bd and Bs meson decay constant have been estimated using the variational method in conjunction with the relativistic Hamiltonian of the heavy meson in the framework of the statistical model. The ratio of CKM matrix elements [Formula: see text] has been extracted from [Formula: see text] mixing using the estimated decay constants and ratio of Bd and Bs mass differences. The results are found to be in good agreement with the existing theoretical and experimental predictions.
