Cold dark matter and primordial superheavy particles

TL;DR

This paper explores the hypothesis that cold dark matter is made of primordial superheavy particles, whose decay contributed to matter formation and whose long-lived component explains high-energy cosmic rays.

Contribution

It investigates the role of superheavy particles in cold dark matter, linking their decay to matter formation and cosmic ray phenomena.

Findings

Decay of short-lived superheavy particles contributed to matter mass.

Long-lived superheavy particles may account for high-energy cosmic rays.

The hypothesis connects dark matter composition with observable cosmic phenomena.

Abstract

The hypothesis that cold dark matter consists of primordial superheavy particles, the decay of short lifetime component of which led to the observable mass of matter while long living component survived up to modern times manifesting its presence in high energetic cosmic rays particles is investigated.
