This talk presents the most recent results on the search for the rare decay B<sup>0</sup><sub>s</sub>→ μ<sup>+</sup>μ<sup>−</sup>, as well asthe latest update on the study of the various angular amplitudes contributing to flavour taggedB<sup>0</sup><sub>s</sub>→ J/ψ(μ<sup>+</sup>μ<sup>−</sup>)ϕ(K<sup>+</sup>K<sup>−</sup>) decays. The latter analysis measures the CP-violating phase ϕ<sub>s</sub>, as well as the average B<sub>s</sub> meson lifetime Γ<sub>s</sub> and the decay width difference ∆Γ<sub>s</sub>.
