Measurement of φs at D0 Experiment

Recent measurements of the D0 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 3.2σ deviation from the SM prediction, while the updated study of the Bs → 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 D0 collaboration has much more statistics to analyze, and all these results can be significantly improved in the future.
