Dispersive analysis of Λ b → Λ(1520) local form factors

Abstract We perform an analysis of Λ b → Λ(1520) local form factors. We use dispersive techniques to provide a model-independent parametrisation of the form factors that can be used in the whole kinematic region. We use lattice QCD data to constrain the free parameters in the form factors expansion,...
