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…

Highly accurate results from frequency measurements on neutral hydrogen molecules H_2, HD and D_2 as well as the HD^+ ion can be interpreted in terms of constraints on possible fifth-force interactions. Where the hydrogen atom is a probe…

If electroweak symmetry breaking is a consequence of color sextet quark chiral symmetry breaking, dramatic, large cross-section, effects are to be expected at the LHC - with the pomeron playing a prominent role. The symmetry breaking is…
