Heavy states of hadron string as weak interacting massive particles for Dark Matter

TL;DR

This paper proposes that heavy hadron string states with masses around 10 GeV or more, which interact very weakly with ordinary matter and have lifetimes exceeding the age of the universe, could serve as candidates for dark matter in the form of WIMPs.

Contribution

It introduces a novel candidate for dark matter based on heavy hadron string states with extremely small coupling constants and long lifetimes.

Findings

Heavy hadron string states can have masses around 10 GeV or more.

These states have very small coupling constants with ordinary baryons.

Their mean lifetimes can exceed the age of the universe.

Abstract

Massive states (of order 10 Gev and more) of hadron string (with scale 1 Gev) can have very small coupling constants with usual baryons of the Universe. Corresponding mean times for them are found to be order and even more than the age of the Universe. They are proposed as possible candidates for weak interacting massive particles (WIMP) of Dark Matter.
