Short- vs. long-distance physics in $$b ightarrow k^{(*)} ell ^+ell ^-$$: a data-driven analysis

HIGHLIGHTS

• What: The aim of this paper is to extract additional information from data that can shed light on the origin of this tension. By doing so, the authors determine the residual amplitude sensitive to charm re-scattering, both as a function of q 2 and as a function of the specific hadronic transition. The authors implement this shift in all C7 terms in Eq (2.8).2 The leading contribution is provided by single-pArticle intermediate states with the correct quantum numbers and valence quarks, namely the spin-1 charmonium resonances (V=J/ψ, ψ(2 S),...).
