Abstract

The axion is a hypothetical particle being of interest as a possible component of the cold dark matter. The axion-like dark matter interacts with particles as axions. The axion–gluon coupling results in the appearance of oscillating nucleon EDMs which are proportional to the axion field. Axions manifest themselves in direct interactions with particles (the so-called axion wind effect). The axion–photon coupling leading to the appearance of effective oscillating magnetic charges and EDMs also influences the spin motion. We determine the relativistic spin dynamics defined by the pseudoscalar field of dark matter axions.
