On the possible role of superheavy particles in the early Universe

TL;DR

This paper investigates models where superheavy particles formed in the early Universe decay into lighter particles, predicting observable baryon and entropy numbers and exploring their potential role in creating cold dark matter.

Contribution

It introduces models of superheavy particle creation and decay in the early Universe, linking them to baryon asymmetry, entropy, and dark matter formation.

Findings

Predicted observable baryon and entropy numbers.

Explored superheavy particles as a source of cold dark matter.

Analyzed decay processes of superheavy particles in early Universe.

Abstract

Different models of the role of creation of superheavy particles in the early Friedmann Universe with their subsequent decay on light particles are investigated. The observable numbers of baryon and entropy are predicted. The possible role of superheavy particles in creation of cold dark matter is discussed.
