摘要：
We consider the isospin-breaking corrections to charmless semileptonic decays of B mesons. Both the recently measured branching ratios of exclusive decays by the CLEO Collaboration and the end-point region of the inclusive lepton spectrum in form factor models can be affected by these corrections. Isospin corrections can affect the determination of \V-nb\ from exclusive semileptonic B decays at a level comparable to present statistical uncertainties.
