Short- vs. long-distance physics in $$B\rightarrow K^{(*)} \ell ^+\ell ^-$$ B → K ( ∗ ) ℓ + ℓ - : a data-driven analysis
Abstract We analyze data on $$B\rightarrow K\mu ^+\mu ^-$$ B → K μ + μ - and $$B\rightarrow K^*\mu ^+\mu ^-$$ B → K ∗ μ + μ - decays in the whole dilepton invariant mass spectrum with the aim of disentangling short- vs. long-distance contributions. The sizable long-distance amplitudes from $$c \over...
