Analyticity properties and unitary constraints on heavy meson form factors

# metadata.dc.description.abstract[].value
We derive new bounds on the b-number forro factor F(q2 ) of the B meson for q2 values relevant to the kinematics of the decays B ➔ Dlv1 and B ➔ n•tv1. The new bounds take into account the experimentally known properties of the T states below the onset of the physical BB threshold.
