Matter-antimatter asymmetry and chiral behavior in perturbed atom H.

Recently, we showed 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 of 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) world and the antihydrogen (antimatter) anti-world is governed by number 2me/mH= 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-anti-fermion symmetry and defies Einstein's Special Theory of Relativity (STR).
