Dual unified SU(5)

TL;DR

This paper explores a duality-based approach to grand unification, proposing electric Seiberg-duals of the minimal supersymmetric SU(5) GUT that could explain the absence of proton decay and incorporate supersymmetry breaking.

Contribution

It introduces electric Seiberg-duals for the minimal supersymmetric SU(5) GUT, providing a novel duality framework that addresses proton decay and unification.

Findings

Proposes dual models with Landau poles below GUT scale

Constructs an asymptotically free SU(11)xSp(1)^3 dual model

Integrates gauge-mediated metastable supersymmetry breaking

Abstract

Despite the compelling simplicity of minimal supersymmetric unification, the proton does not decay as predicted. A possible explanation is that real unification takes place in a theory which is an electric dual of the MSSM GUT with messengers, which has Landau poles below the GUT scale. As was recently pointed out, unification predictions would be transmitted across such a duality, but proton decay would be negligible. In this paper we present electric Seiberg-duals for the minimal supersymmetric SU(5) GUT (plus messengers) that realise this idea, one particularly nice example being an asymptotically free SU(11)xSp(1)^3 model. We also discuss how gauge-mediated metastable supersymmetry breaking can be incorporated into an overall unified picture.
