On the Issue of Detection of Dark Matter Particles

Analyzing the spectra of ultrahigh-energy cosmic rays (photons), confirmation of the existence of new particles—the X17 and X38 bosons, with masses of 17 and 38 MeV, respectively, has been found. These particles are not included in the Standard Model. They were discovered earlier in experiments on accelerators. In the present paper, the thermodynamic approach is applied to obtain independent confirmation of the existence of these particles, which are candidates for the role of dark matter particles.
