Particle and Nuclear Theory Seminar- Global Analysis of b->c Form Factors

Abstract: In recent years, discrepancies have arisen between the theoretical predictions and experimental measurement of the semileptonic decays of heavy mesons.  Near-term experiments anticipate further refinement of their measurements, as well as a new observables probing these interactions.  At present, some of these new observables lack rigorous predictions from lack of input from lattice QCD into the underlying hadronic form factors.  In this talk, I will discuss how dispersion relations and heavy quark symmetries can be used to fill in the gaps from lattice QCD to make predictions for these form factors.
