Semileptonic form factors – a model-independent approach

Abstract

We demonstrate that the B → D(∗)lν form factors can be accurately predicted given the slope parameter ρ2 of the Isgur-Wise function. Only weak assumptions, consistent with lattice results, on the wavefunction for the light degrees of freedom are required to establish this result. We observe that the QCD and 1 mQ corrections can be systematically represented… (More)
