Abstract
Axion-like dark matter interacts with particles like an axion. The axion is a hypothetical particle being a quant of pseudoscalar field. It has been originally postulated by Peccei and Quinn in 1977 to resolve the strong \(CP\) problem in QCD. If axions exist, they are of interest as a possible component of cold dark matter. The axion photon coupling distorts the electromagnetic field and leads to the inverse Primakoff effect which can be observed with haloscopes. \(CP\)-noninvariance of the axion-gluon coupling results in an appearance of oscillating nucleon EDMs which are proportional to the axion field. Axions manifest themselves in direct interactions with particles (so-called axion wind effect). We rigorously determine the relativistic spin dynamics defined by the pseudoscalar field of dark matter axions.
期刊介绍：
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
