Magnetic Quarks and Electric Quarks in Hadrons

Dirac's magnetic monopoles are generalized to have aspects which are similar to the conventional quarks (electric quarks). Such magnetic monopoles are called magnetic quarks. This work assumes that a baryon consists of three solid bodies called electromagnetic quarks, and that an electromagnetic quark and an electromagnetic antiquark form a meson. Each of these electromagnetic quarks is considered to be composed of one electric quark and one magnetic antiquark. Such a speculation solves the difficulty in statistics faced by the paraquark model and allows the existence of anomalous charge conjugation parity $C$ of mesonic states. New baryon mass relations and magnetic moments have been derived. Finally, a strong electric dipole moment is predicted to exist in a baryon state with nonzero electromagnetic-quark orbital angular momentum, $L\ne 0$.
