Long-distance effects in $$B\rightarrow K^*\ell \ell $$ B→K∗ℓℓ from analyticity
Abstract We discuss a novel approach to systematically determine the dominant long-distance contribution to $$B\rightarrow K^*\ell \ell $$ B→K∗ℓℓ decays in the kinematic region where the dilepton invariant mass is below the open charm threshold. This approach provides the most consistent and reliabl...
