论文摘要
变形的相对论运动学预计将以平坦的量子重力限制出现，可预测在普朗克质量附近的能量尺度上违反离散对称性。 C，P和T不变性的动量依赖性变形源自\ k {appa}的poincaré代数。 CPT对称性的变形导致对Lorentz对称性的微妙侵犯。这需要一些小但可衡量的现象学后果，作为对时间演化特征的校正：高能量处的两粒子状态的粒子寿命或风味振荡的频率。我们在这里争辩说，使用MUON寿命上的当前实验精度可以绑定LHC Energy处的变形参数\ K {Appa}> 10^14 GEV，甚至将此极限移至未来圆形碰撞器的10^16 GEV，该cern计划在CERN。也可以从中性介子的干扰中获得变形的较弱极限。在攻势的b0中，它相当于\ k {appa}> 10^8 GEV在99％的置信度级别为99％。
Deformed relativistic kinematics, expected to emerge in a flat-spacetime limit of quantum gravity, predicts violation of discrete symmetries at energy scale in the vicinity of the Planck mass. Momentum-dependent deformations of the C, P and T invariance are derived from the \k{appa}-deformed Poincaré algebra. Deformation of the CPT symmetry leads to a subtle violation of Lorentz symmetry. This entails some small but measurable phenomenological consequences, as corrections to characteristics of time evolution: particle lifetimes or frequency of flavour oscillations in two-particle states at high energy. We argue here that using current experimental precisions on the muon lifetime one can bound the deformation parameter \k{appa} > 10^14 GeV at LHC energy and move this limit even to 10^16 GeV at Future Circular Collider, planned at CERN. Weaker limits on deformation can be also obtained from interference of neutral mesons. In case of B0s from Υ decay it amounts to \k{appa} > 10^8 GeV at confidence level 99%.
