Frozen SUSY with Susyons as the Dark Matter

TL;DR

Frozen SUSY is a highly constrained supersymmetric GUT model predicting a stable, gravitationally interacting particle called Susyon, which could serve as a dark matter candidate, while improving mass predictions and cosmological constant estimates.

Contribution

It introduces a minimal, highly predictive version of SUSY GUT with only one additional particle, the Susyon, and explores its implications for dark matter and cosmology.

Findings

Susyon is stable and interacts only gravitationally.

Frozen SUSY predicts 14 particle masses with only 4 parameters.

The model offers improved predictions for the cosmological constant.

Abstract

Frozen SUSY is the maximally suppressed Supersymmetric SU(5) Grand Unified Theory coupled to Supergravity. In Frozen SUSY, there is only one extra particle in addition to those that appear in the usual non-supersymmetric SU(5) Grand Unified Theory coupled to gravity. Frozen SUSY also restricts and improves the mass predictions, and the cosmological constant (at tree level). As a result, it uses 4 parameters to generate 14 reasonable predicted masses. The one extra particle is an extremely massive gravitino, which we call the Susyon. In Frozen SUSY, the Susyon is stable and it interacts purely through gravity. The Susyon might be a viable candidate for dark matter.
