Description

The observed CP and T violations in neutral Kaons experiments are explained as an interplay between two oscillations in the earth’s Schwarzschild geometry: (i) mixing associated with second order weak coupling and (ii) strange quark’s zitterbewegung: https://doi.org/10.48550/arXiv.2403.07970 and https://doi.org/10.48550/arXiv.2403.07703. This violation is in fact a CPT violation with T conservation rather than the usual interpretation as a T violation with CPT conservation. The main results of this study are: (i) the origin of indirect and direct CP violations is identified, (ii) the measured values of the CP violations parameters e and e’ are predicted in agreement with the experimental values, and (iii) the right status of the symmetry violation induced by spacetime curvature is restored. The difference between microscopic and macroscopic time reversal violations is stressed as a source of confusion and the restoration of T conservation at the microscopic level provides an improved framework for elementary particles physics. Beside particles physics, these results are of  broad appeal, particularly in cosmology as the understanding of the origin of CP violation might help to explain how our matter dominated universe emerged during its early evolution.
