Spectra of Secondary Particles in High-Energy Proton–Proton Collisions in the Thermodynamic Model and the Possibility of Detection of Particles of Dark Matter

Abstract

In a simple thermodynamic model, transverse momentum distributions are found for $$\Lambda $$ -hyperons produced in pp collisions at ultrarelativistic energies. Studying the behavior of the average transverse momentum depending on the mass of the emitted particle shows that it is possible to search for large mass quark nuggets as possible candidates for the role of dark matter particles. An interpretation of the spectra of soft photons with respect to the transverse momentum in pp collisions is also given taking into account the boson X17, a new particle, a possible candidate for the role of dark matter particles.
