Hierarchies of Susy Splittings and Invisible Photinos as Dark Matter

TL;DR

This paper investigates how hierarchies in supersymmetric partner splittings can lead to invisible particles that contribute to dark matter and influence early universe cosmology.

Contribution

It introduces mechanisms for generating hierarchies in superpartner splittings and explores their implications for dark matter and cosmological phenomena.

Findings

Existence of invisible dark matter components

Potential new inflaton candidates

Invisible particles affecting early universe epochs

Abstract

We explore how to generate hierarchies in the splittings between superpartners. Some of the consequences are the existence of invisible components of dark matter, new inflaton candidates, invisible monopoles and a number of invisible particles that might dominate during various eras, in particular between BBN and recombination and decay subsequently.
