  Recently, we showed that that band as well as line spectra, reveal a
left-right symmetry in 4- and 2-fermion systems. We now show how a
mass-conjugation explains the difference between atom- and antiatom-states in a
stable 2-unit charge Coulomb system. For the electron-proton system in natural
H, this difference (an anomaly) between states belonging to the hydrogen
(matter) and the antihydrogen (antimatter) anti-world is governed by number
2m(e)/m(H) = 0.0011. This is verified with the H-line spectrum. Classical
physics can describe the parity effects for matter-antimatter asymmetry. An
internal mass-conjugation (internal algebra) extends and generalizes Dirac's
fermion-antifermion symmetry and defies Einstein's Special Theory of Relativity
(STR).
