Description
The CP violating phase $\phi_S$ arises in the interference between the amplitudes of $B_s^0$ mesons decaying via $b \rightarrow s$ transition and those decaying after oscillation. The flavour tagging methods of $B_s^0$ has significant impact on the precision of the $\phi_s$ phase studies.
This talk will be focused on the procedure of the calibration of opposite side tagging method using $B^{\pm}$ decays and its implementation into the $B_s^0 \rightarrow J/\psi \phi$ measurements.
