Fermion-Boson-Type Subquark Model and F2-Changing Phenomena

The mass differences in all neutral pseudo scalar mesons and CP violations associated with the mixings are investigated in the context of the fermion- boson-type subquark model. These phenomena are unifyingly explained by the neutral scalar subquark exchanges between two quarks inside the present meson. It is predicted that the mass differences and CP violations of D, B and T meson systems.
