Abstract

The decay mode B⁰_s → D^∓_s K^± allows for one of the theoretically cleanest time dependent measurements of the CKM angle γ. This contribution reports the world best branching fraction of this decay relative to the Cabibbo--favoured mode B⁰_s → D_s^-π⁺ based on data sample of 0.37 \rm fb^-1 proton--proton collisions at √(s) = 7 TeV collected with the LHCb detector in 2011, resulting in BR(\BsDK) = (1.90 ± 0.12^stat ± 0.13^syst+0.12_-0.14^f_s/f_d)× 10^-4.
