Abstract
We study the effects of a modest V+A admixture strength in bâu current in the decay BâÏlν. We have shown that the decay rate, lepton forward-backward distribution asymmetry AFB and polarization ratio are sensitive to the admixture. Future experimental studies of the decay at BaBar and Belle could clarify the chirality of bâu current and might reveal hints for new physics with right-handed quark currents.
