Description

  • Content Description: We point out that current experimental data for partial B {yields} {pi}l{nu} branching fractions reduce the theoretical input required for a precise extraction of |V{sub ub}| to the form-factor normalization at a single value of the pion energy. Different parameterizations of the form factor shape leading to this conclusion are compared and the role of dispersive bounds on heavy-to-light form factors is clarified.
