| Zusammenfassung | The existence of a new spin dependent short-range Yukawa force may be a signature of pseudo-scalar boson particles like the "invisible axion" which is of interest as a possible component of cold dark matter. Originally, the axion was invented by Peccei and Quinn to solve the so-called “strong CP problem”, i.e. presence of CP violating terms (ϑ-term) in the QCD Lagrangian that arise from the non-trivial QCD vacuum structure. Such axions were not found in early searches, ruling out ”standard axions” which have been related to the electroweak scale of symmetry breaking in the original Peccei–Quinn model. However, in case of a much higher energy breaking scale the axion becomes a very light, very weakly coupled and very long-lived particle that is named “invisible axion”. Such hypothetical particle can mediate interaction between fermions which in case of monopole–dipole coupling violates parity and time symmetries. |
