Parity-symmetry, CP violation, K meson decay, Belle experiment, Babar experiment
Abstract
As a matter of fact, the CP violation investigations remain a hot topic in theoretical physics in recent years. With this in mind, this study briefly introduces how three basic discrete symmetries (CPT) are defined, as well as the findings towards the violation of respective P symmetry and combined CP symmetry, with the further indication of T symmetry. At the same time, three experiments are described to provide a full spectrometer of the findings, i.e., Fitch-Cronin experiment, Belle experiment as well as Babar experiment. By analyzing and discussing previous articles and some famous experimental results, the article covers approximately 60 years of Particle physics improvements under one of its branch-CP violation. According to the analysis and estimations, the evaluations of famous experiments along with their settings convey the idea of accuracy of modern particle physics. In the meantime, the current limitations are demonstrated. Overall, these results shed light on guiding further exploration and investigations of CP violation.
