论文摘要
该程序的贡献介绍了$ b_s^0 \在Atlas，CMS和LHCB实验执行的$ B_S^0 \中的CP侵略和其他物理参数的最新测量。这些测量基于在质子质子碰撞中在LHC上收集的数据集，在13 TEV的质量中心能量中。除了违反阶段$ ϕ_s $的CP外，还测量了$ b_ {s}^0 $ b_ {s}^0之间的宽度差。然后将测量值与在8 TEV处收集的值结合。测量与基于标准模型的理论预测一致。
This proceeding contribution presents the latest measurement of the CP-violation and other physics parameters in the $B_s^0 \to J/ψϕ$ decay channel performed by the ATLAS, CMS and LHCb experiments. The measurements are based on a data set collected at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. Besides the CP violating phase $ϕ_s$, the width difference between the $B_{s}^0$ meson mass eigenstates $ΔΓ_s$ and the average decay width $Γ_s$ are measured. The measured values are then combined with those collected at 8 TeV. The measurements are consistent with theoretical predictions based on the Standard Model.
