Description
In this talk, we will present the improved Standard-Model predictions for $K_L \to \ell^+ \ell^-$ decays, making use of a dispersive representation of the underlying transition form factor that incorporates the constraints from the available data and the asymptotic behavior. The precise determinations of the Standard-Model branching fractions will be contrasted with the existing measurements. We will also derive the resulting constraints on physics beyond the Standard Model.
