Model-independent study of B_c → D* ℓℓ decay shows sensitivity of branching fraction, forward-backward asymmetry, and angular observables to New Physics in b→d transitions.
Model-independent calculation of differential branching ratio, forward-backward asymmetry, polarization, and angular coefficients in Bs → K* μ+μ- with 1D and 2D new physics scenarios in C7^NP, C9^(prime)NP, and C10^(prime)NP showing deviations from SM.
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.
