2-COMPONENT SEMILEPTONIC FORM-FACTORS
Journal or Book Title
PHYSICAL REVIEW LETTERS
In the semileptonic decays of a heavy quark to a light quark, present models disagree in an essential fashion concerning the shape of the form factors. Both the heavy quark limit of QCD and dispersion relations suggest that the correct form factors contain two distinct contributions. We discuss these as applied to B→πeν and B→ρeν decays. We also describe the inconsistencies of available phenomenological models and discuss how they must be modified.
