Description
In $B_s^0 \to D_s^{\mp} K^{\pm}$ decays $CP$ violation
in the interference between direct decay and decay after mixing
results in a time-dependent asymmetry of the decay rates.
From a measurement of this asymmetry five $CP$ observables can be determined,
which are themselves sensitive to the CKM angle $\gamma$.
The talk presents the flavour-tagged analysis of the Run I dataset recorded by the LHCb experiment.
