Laboratory tests of the ordinary-mirror particle oscillations and the extended CKM matrix

The CKM matrix and its unitarity is analyzed by disentangling experimental information obtained from three different particle systems of neutrons, mesons, and nuclei. New physics beyond the Standard Model is supported under the new analysis. In particular, the newly proposed mirror-matter model [Phys. Lett. B 797, 134921 (2019)] can provide the missing physics and naturally extend the CKM matrix. Laboratory experiments with current technology for measuring neutron, meson, and nuclear decays under various scenarios are proposed. Such measurements can provide stringent tests of the new model and the extended CKM matrix.
