论文摘要
我们对界限的界限进行了系统的研究，该界限可以从相对论对称性的Planck尺度变形和CPT中，并从粒子和反粒子寿命的精确测量中进行。详细阐述了我们的早期工作[1]，我们讨论了一种从CPT不变性的新形式，该出发与非平凡的几何形状有关，及其对粒子和反颗粒质量壳和衰减概率的后果。我们的主要结果是基于当前数据和高能实验的敏感性所考虑的理论模型的变形参数，可以获得实验界限的集合。
We carry out a systematic study of the bounds that can be set on Planck-scale deformations of relativistic symmetries and CPT from precision measurements of particle and antiparticle lifetimes. Elaborating on our earlier work [1] we discuss a new form of departure from CPT invariance linked to the possibility of a non-trivial geometry of four-momentum and its consequences for the particle and antiparticle mass-shells and decay probabilities. Our main result is a collection of experimental bounds that can be obtained for the deformation parameter of the theoretical model under consideration based on current data and sensitivities of planned experiments at high energies.
