Analyticity properties and unitary constraints on heavy meson form factors

Rafael, Eduardo deTaron i Roca, Josep2010-05-062010-05-0619940556-2821https://hdl.handle.net/2445/12424We 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.8 p.application/pdfeng(c) The American Physical Society, 1994Partícules (Física nuclear)Particles (Nuclear physics)Analyticity properties and unitary constraints on heavy meson form factorsinfo:eu-repo/semantics/article121449info:eu-repo/semantics/openAccess
