Charged B Meson

The effect of magnetic fields on the leptonic decay of charged B meson B− → l-v- is investigated. The decay rate of the process is calculated both in the absence and presence of magnetic field. The non-perturbative parameters fB± (B), f'B± and MB±(B) are also estimated.

Charged B Meson

We report results of a search for B→τν in a sample of 9.7 million charged B meson decays. The search uses both πν and [Formula: see text] decay modes of the τ, and demands exclusive reconstruction of the companion [Formula: see text] decay to suppress background. We set an upper limit on the branching fraction ℬ(B→τν)<8.4×10-4 at 90% confidence level. With slight modification to the analysis we also establish [Formula: see text] at 90% confidence level.

Factorizable Contribution

We investigate [Formula: see text] decay in perturbative QCD approach which has recently been applied to B-meson decays. [Formula: see text] decay (and its charge conjugated mode) can be one of the hopeful modes to determine |Vub| since it occurs through b → u transition only. We estimate both factorizable and non-factorizable contribution, and show that the non-factorizable contribution is much less than the factorizable one. Our calculation gives [Formula: see text].
