用J-PET探测器检验正电子偶素衰变的离散对称性

Testing Discrete Symmetries in Ortho-Positronium Decays with the J-PET Detector

Eryk Czerwiński

摘要:

根据J-PET探测器收集的数据,已经获得了与正电子偶素衰变CPT测试有关的第一个结果,并且正在研究CP对称性的新测试。这两个结果都是基于确定的角动量的伽马射线和其他矢量属性的调查系统之间的相关性。在这里,参数的可能使用的数据收集的J-PET组测试CPT对称性的标准模型扩展框架内,很快提出。

英文摘要:

A first result related to a CPT test in the decay of ortho-positronium based on data collected by means of the J-PET detector is already available, and a new test of CP symmetry is under investigation. Both results are based on the determination of angular correlations between momenta of gamma rays and other vector properties of the investigated system. Here, arguments for the possible usage of data collected by the J-PET group to test CPT symmetry within the Standard-Model Extension framework are shortly presented.
