  The phase $\Phi_s$ is the key parameter for the CP-violation of the
$B^0_s$-$\bar{B^0_s}$ system. An angular and proper decay time analysis is
applied to the $B^0_s \rightarrow J/\psi \Phi$ events. Using a data sample
collected by the CMS and ATLAS experiments in LHC Run1, the $B^0_s$ signal
candidates are reconstructed and are used to extract the phase $\Phi_s$. We
present the latest update on the results in this decay channel.
