    "abstract": "Recently, we showed that that band as well as line spectra, reveal a\nleft-right symmetry in 4- and 2-fermion systems. We now show how a\nmass-conjugation explains the difference between atom- and antiatom-states in a\nstable 2-unit charge Coulomb system. For the electron-proton system in natural\nH, this difference (an anomaly) between states belonging to the hydrogen\n(matter) and the antihydrogen (antimatter) anti-world is governed by number\n2m(e)/m(H) = 0.0011. This is verified with the H-line spectrum. Classical\nphysics can describe the parity effects for matter-antimatter asymmetry. An\ninternal mass-conjugation (internal algebra) extends and generalizes Dirac\u0027s\nfermion-antifermion symmetry and defies Einstein\u0027s Special Theory of Relativity\n(STR).",
