Dark Matter In Minimal Trinification

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We study an example of Grand Unified Theory (GUT), known as trinification, which was first introduced in 1984 by S.Glashow. This model has the GUT gauge group as [SU(3)]3[SU(3)]^3 with a discrete Z3\mathbb{Z}_3 to ensure the couplings are unified at the GUT scale. In this letter we consider this trinification model in its minimal formulation and investigate its robustness in the context of cosmology. In particular we show that for a large set of the parameter space the model doesn't seem to provide a Dark Matter candidate compatible with cosmological data.
