On the origin of CP symmetry violations

TL;DR

The work argues that CP violation originates from gravity via a coupling between quark zitterbewegung and meson flavor oscillations, analyzed within the LOY framework augmented by Newtonian gravity. This gravity-induced mechanism generates the three canonical CPV effects in kaon and B-meson systems, yielding predictions for $\mathrm{Re}\varepsilon$, $\mathrm{Re}(\varepsilon'/\varepsilon)$ and $\sin 2β$ that align with experimental values without adjusting CKM CPV parameters. A key claim is that the CKM CPV phase should vanish in flat spacetime, with Earth's gravity providing the observed CPV signals, and that the linear dependence on gravity opens a pathway to cosmological baryogenesis scenarios. The framework is extended to other neutral mesons and suggests deep implications for CPV in a curved spacetime, offering a gravity-centric alternative to the standard CKM interpretation without introducing new fields or free parameters.

Abstract

Experiments devoted to charge parity (CP) violation are normally interpreted by adjusting the elements of the Cabibbo-Kobayashi-Maskawa matrix to the measured violation parameters. However, the physical origin of these violations remains an open issue. To resolve this issue, the impact of Earth's gravity on meson oscillations is analysed. The effect of gravity is to couple flavour oscillations to quark zitterbewegung oscillations, and this coupling induces a superposition of CP eigenstates. The three types of CP violation effects result from this gravity-induced mixing. The three associated violation parameters are predicted in agreement with experimental data. The amplitude of the violation is linear with respect to gravity, so this new mechanism allows us to envisage cosmological evolutions that provide the observed baryonic asymmetry of the universe.
