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.

Introduces a reconstructible angular distribution for B to D* tau nu decays via tau to lepton chain to extract new physics parameters, projecting 5-6% sensitivities from simulation and lattice form factors.
Silicon tracker PID suppresses backgrounds well for low-momentum b-tagging but requires drift-chamber cluster counting for high-momentum s-jet tagging, with 30 ps timing needed to improve rare b to s decay contamination by an order of magnitude over kinematics alone.
LHCb reports updated FCNC decay measurements including a legacy analysis of B0 to K*0 mu+ mu- using 8.4 fb-1 of Run 1 and 2 data, noting persistent tensions with SM expectations in b to s mu mu channels.
A U(1)_{Le-Lμ} extended SM with scalar leptoquark explains b→s anomalies via Z', leptoquark and new fermions while the lightest neutral fermion serves as DM, with constraints analyzed from B decays and DM observables.
