Abstract

Measurements of mixing and CP violation in b-hadron decays are great probes to search for physics beyond the Standard Model. A selection of recent results based upon 3.0 fb^-1 of LHCb data are presented. These are the first measurement of the CP violating phase ϕ_s using B_s⁰→ J/ψK⁺K^- in the mass region above the ϕ(1020) resonance and B_s⁰→ ψ(2S) ϕ decays, the determination of B_s⁰ lifetime using B_s⁰→ D^(*)-μ⁺ν_μ decays, the updated measurements of the CKM angle γ with B^±→ D K^*± and B_s⁰ → D_s^∓K^± decay modes and the CP violation searches in \varLambda⁰_b→ pπ^-π⁺π^- and \varLambda⁰_b→ pK^-μ⁺μ^- decays.
