The decay B s→ μ+ μ− in the Standard Model is generated by the well-known W-box and Z-penguin diagrams that give rise to an effective quark-lepton operator Q A at low energies. We compute QCD corrections of orderto its Wilson coefficient C A. It requires performing three-loop matching between the full and effective theories. Including the new corrections makes C A more stable with respect to the matching scale μ 0 at which the top-quark mass and α s are renormalized. The corresponding uncertainty in| C A| 2 gets reduced from around 1. 8% to less than 0. 2%. Our results are directly applicable to all the B s (d)→ ℓ+ ℓ− decay modes.
