Dispersive analysis of Λ$_{b}$ → Λ(1520) local form factors
We perform an analysis of $\Lb\to\L(1520)$ 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, which...
