@article{Ellis2019SupersymmetricPD, title={Supersymmetric proton decay revisited}, author={John Ellis and Lyndon R Evans and Natsumi Nagata and Keith A. Olive and Liliana Velasco-Sevilla}, journal={The European Physical Journal C}, year={2019}, volume={80}, pages={1-30} }

Encouraged by the advent of a new generation of underground detectors – JUNO, DUNE and Hyper-Kamiokande – that are projected to improve significantly on the present sensitivities to various baryon decay modes, we revisit baryon decay in the minimal supersymmetric SU(5) GUT. We discuss the phenomenological uncertainties associated with hadronic matrix elements and the value of the strong coupling $$\alpha _s$$ α s – which are the most important – the weak mixing angle $$\theta _W$$ θ W , quark… Expand

Abstract
While the observation of nucleon decay would be a smoking gun of Grand Unified Theories (GUTs) in general, the ratios between the decay rates of the various channels carry rich information… Expand

Light-cone sum rules for proton decay

- Physics

We estimate the form factors that parametrise the hadronic matrix elements of proton-to-pion transitions with the help of light-cone sum rules. These form factors are relevant for semi-leptonic… Expand

Product group unification is an attractive alternative to simple grand unification. It solves the infamous doublet-triplet splitting problem and the dimension-5 proton decay problems without… Expand

Building models of inflation in no-scale supergravity

- Physics, Mathematics
- 2020

After reviewing the motivations for cosmological inflation formulated in the formalism of supersymmetry, we argue that the appropriate framework is that of no-scale supergravity. We then show how to… Expand

Low-energy probes of no-scale SU(5) super-GUTs

- Physics

We explore the possible values of the $\mu \to e \gamma$ branching ratio, $\text{BR}(\mu\rightarrow e\gamma)$, and the electron dipole moment (eEDM), $d_e$, in no-scale SU(5) super-GUT models with… Expand

Model of metastable EeV dark matter

- Physics

We propose a model where a long-lived pseudoscalar EeV particle can be produced with sufficient abundance so as to account for the cold dark matter density, despite having a Planck mass suppressed… Expand

Observable proton decay in flipped SU(5)

- Physics

We explore proton decay in a class of realistic supersymmetric flipped $SU(5)$ models supplemented by a $U(1)_R$ symmetry which plays an essential role in implementing hybrid inflation. Two distinct… Expand
