Measurement of $\phi_s$ at D{\O} Experiment
  Recent measurements of the D\O\ experiment related to the search for new phenomena beyond the Standard Model are reviewed. The new measurement of the like-sign dimuon charge asymmetry reveals a 3.2$\sigma$ deviation from the SM prediction, while the updated study of the $B_s \to J/\psi \phi$ decay demonstrates a better agreement with the SM. All experimental results on the $CP$ violation in mixing are currently consistent with each other. The D\O\ collaboration has much more statistics to analyze, and all these results can be significantly improved in the future.
