Query: Study of Anomalies in Exclusive Semileptonic B Decays   Our Vcb extraction is based on recent Belle results, with unfolded
kinematical dependence. We use two different parameterizations of the form
factors, the CLN and BGL parameterizations. We discuss how the known
discrepancy between the inclusive and exclusive determinations of Vcb depends
on an underestimate of the uncertainty with parameterizations that use heavy
quark expansion.
  We investigate the results of the semileptonic B decay with heavy leptons
(tau) compared to the decays into light leptons. Experimental ratio of the two
branching ratios is systematically larger than the Standard Model(SM)
prediction. Effects of new physics operators on the data about these decays are
studied.
