A symmetry-guided phenomenological model organizes leading current-current operators for charged-current decays of heavy-light mesons and reproduces heavy-quark scaling relations for decay constants and form factors.
R_K*0 is measured as 1.08^{+0.14}_{-0.12}(stat) ± 0.07(syst) for q² > 14 GeV²/c⁴ in B⁰ → K*⁰ ℓ⁺ℓ⁻ decays, consistent with the Standard Model.
The LFU ratio R_Λ^{τ/μ} for Λ_b → Λ τ⁺τ⁻ is predicted in the SM with below-10% uncertainty and can be enhanced by several orders of magnitude in EFT models motivated by b→cτν and b→sμμ anomalies.
Weak annihilation contributions are sizable in B_c^+ to D^{*+} lepton pair decays and must be included to obtain reliable Standard Model predictions for angular observables.
