Two Loop R-Symmetry Breaking

TL;DR

This paper investigates how two-loop quantum corrections can lead to spontaneous R-symmetry breaking in non-supersymmetric vacua within O'Raifeartaigh-like models, with potential implications for phenomenology.

Contribution

It demonstrates that R-symmetry can be broken at two loops in non-supersymmetric vacua and provides a basic example illustrating this phenomenon.

Findings

R-symmetry can be spontaneously broken at two loops

A basic model exhibiting this behavior is presented

Implications for phenomenological models are discussed

Abstract

We analyze two loop quantum corrections for pseudomoduli in O'Raifeartaigh like models. We argue that R-symmetry can be spontaneously broken at two loop in non supersymmetric vacua. We provide a basic example with this property. We discuss on phenomenological applications.
