Measurement of $ϕ_s$ at DØ Experiment

Recent measurements of the DØ 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$σ$ deviation from the SM prediction, while the updated study of the $B_s \to J/ψϕ$ decay demonstrates a better agreement with the SM. All experimental results on the $CP$ violation in mixing are currently consistent with each other. The DØ collaboration has much more statistics to analyze, and all these results can be significantly improved in the future.
