A flavor-tagged time-dependent angular analysis of the decay B_{s}^{0}→ϕϕ is performed using pp collision data collected by the LHCb experiment at the center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 6 fb^{-1}. The CP-violating phase and direct CP-violation parameter are measured to be ϕ_{s}^{ss[over ¯]s}=-0.042±0.075±0.009 rad and |λ|=1.004±0.030±0.009, respectively, assuming the same values for all polarization states of the ϕϕ system. In these results, the first uncertainties are statistical and the second systematic. These parameters are also determined separately for each polarization state, showing no evidence for polarization dependence. The results are combined with previous LHCb measurements using pp collisions at center-of-mass energies of 7 and 8 TeV, yielding ϕ_{s}^{ss[over ¯]s}=-0.074±0.069 rad and |λ|=1.009±0.030. This is the most precise study of time-dependent CP violation in a penguin-dominated B meson decay. The results are consistent with CP symmetry and with the standard model predictions.
利用大型强子对撞机底夸克实验（LHCb）在质心能量为13 TeV时收集的质子-质子碰撞数据，对应积分亮度为6 fb⁻¹，对衰变Bₛ⁰→ϕϕ进行了味标记的时间相关角分析。假设ϕϕ系统所有极化态的值相同，测得CP破坏相位和直接CP破坏参数分别为ϕₛˢˢ[上划线s]= -0.042±0.075±0.009 rad和|λ| = 1.004±0.030±0.009。在这些结果中，第一个不确定度是统计性的，第二个是系统性的。这些参数也针对每个极化态分别确定，未显示出极化依赖性的证据。这些结果与LHCb先前在质心能量为7和8 TeV时使用质子-质子碰撞的测量结果相结合，得到ϕₛˢˢ[上划线s]= -0.074±0.069 rad和|λ| = 1.009±0.030。这是对企鹅主导的B介子衰变中时间相关CP破坏的最精确研究。结果与CP对称性和标准模型预测一致。
