Constraints on Heavy Meson Form Factors Derived from QCD Analyticity, Unitarity and Heavy Quark Spin Symmetry
Abstract
Using the analytic properties of two-point functions in QCD, as well as unitarity, bounds on the B meson form factor F(q2) can be derived. Heavy quark spin symmetry, correctly taken into account, is shown to improve these bounds significantly.
