论文摘要
在使用宙斯$ e^{\ pm} p $数据的有效场理论的背景下，研究了标准模型夸克部门中的Lorentz和CPT对称性。对称侵略效应可以导致原本与时间独立的可观察到的时间依赖性振荡，包括散射横截面。使用五年的包含中性的深层非弹性散射事件进行分析，该事件对应于$ 372 \ $ 372 \的综合HERA光度； \ text {pb}^{ - 1} $ at $ \ sqrt {s} = 318 $ gev已执行。在统计和系统的不确定性中，没有观察到恒星时间振荡的证据。大多数限制首次放置在42个系数上，参数占主导地位的cpt-even尺寸为前四和cpt-odd尺寸五个尺寸五旋转旋转非依赖性的修饰，以对光夸克的传播和相互作用。
Lorentz and CPT symmetry in the quark sector of the Standard Model are studied in the context of an effective field theory using ZEUS $e^{\pm} p$ data. Symmetry-violating effects can lead to time-dependent oscillations of otherwise time-independent observables, including scattering cross sections. An analysis using five years of inclusive neutral-current deep inelastic scattering events corresponding to an integrated HERA luminosity of $372\; \text{pb}^{-1}$ at $\sqrt{s} = 318$ Gev has been performed. No evidence for oscillations in sidereal time has been observed within statistical and systematic uncertainties. Constraints, most for the first time, are placed on 42 coefficients parameterising dominant CPT-even dimension-four and CPT-odd dimension-five spin-independent modifications to the propagation and interaction of light quarks.
