Hyperphoton

A hyperphoton is a hypothetical particle^[1] with a very low mass and spin equal to one. The hypothesis of the existence of hyperphotons is an explanation for the violation of CP-invariance in the two-pion decay of a long-lived neutral kaon ${\displaystyle K_{L}^{0}\rightarrow \pi ^{+}+\pi ^{-}}$.^[2][3][4] According to this hypothesis, there is a long-range very weak field generated by hypercharged particles (for example, baryons), whose quantum carrier is a hyperphoton, which acts differently on ${\displaystyle K^{0}}$ and ${\displaystyle {\hat {K^{0}}}}$ mesons whose hypercharges differ in signs.
