Violations of CPT symmetry and Lorentz invariance are searched for by studying interference effects in B^{0} mixing and in B_{s}^{0} mixing. Samples of B^{0}→J/ψK_{S}^{0} and B_{s}^{0}→J/ψK^{+}K^{-} decays are recorded by the LHCb detector in proton-proton collisions at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb^{-1}. No periodic variations of the particle-antiparticle mass differences are found, consistent with Lorentz invariance and CPT symmetry. Results are expressed in terms of the standard model extension parameter Δa_{μ} with precisions of O(10^{-15}) and O(10^{-14}) GeV for the B^{0} and B_{s}^{0} systems, respectively. With no assumption on Lorentz (non)invariance, the CPT-violating parameter z in the B_{s}^{0} system is measured for the first time and found to be Re(z)=-0.022±0.033±0.005 and Im(z)=0.004±0.011±0.002, where the first uncertainties are statistical and the second systematic.
通过研究(B^{0})混合和(B_{s}^{0})混合中的干涉效应来寻找CPT对称性和洛伦兹不变性的违反情况。在大型强子对撞机底夸克探测器（LHCb）中，于质心能量为7和8 TeV的质子 - 质子碰撞中记录(B^{0}\to J/\psi K_{S}^{0})和(B_{s}^{0}\to J/\psi K^{+}K^{-})衰变的样本，对应积分亮度为(3,\text{fb}^{-1})。未发现粒子 - 反粒子质量差的周期性变化，这与洛伦兹不变性和CPT对称性一致。结果分别以标准模型扩展参数(\Delta a_{\mu})表示，对于(B^{0})和(B_{s}^{0})系统，精度分别为(O(10^{-15}))和(O(10^{-14}),\text{GeV})。在不对洛伦兹（非）不变性做任何假设的情况下，首次测量了(B_{s}^{0})系统中违反CPT的参数(z)，发现其实部(\text{Re}(z)= -0.022\pm0.033\pm0.005)，虚部(\text{Im}(z)= 0.004\pm0.011\pm0.002)，其中第一个不确定度是统计性的，第二个是系统性的。
