Diphoton Resonance in F-theory inspired Flipped SO(10)

TL;DR

This paper proposes an F-theory inspired flipped SO(10) GUT model to explain the 750 GeV diphoton excess, incorporating vectorlike triplets and singlets that could produce the observed resonance.

Contribution

It introduces a novel F-theory based flipped SO(10) model embedding in E6, explaining the diphoton excess with specific low-energy spectrum features.

Findings

Model can produce a multi-GeV decay width for the resonance.

Includes vectorlike triplets and singlets relevant for the diphoton signal.

Provides a theoretical framework consistent with LHC observations.

Abstract

Motivated by the diphoton excess at 750 GeV reported by the ATLAS and CMS experiments, we present an F-theory inspired flipped $SO(10)$ model embedded in an $E_6$ GUT. The low energy spectrum includes the three MSSM chiral families, vectorlike color triplets, several pairs of charged $SU(2)_L$ singlet fields $(E^c, \bar E^c)$, as well as MSSM singlets, one or more of which can contribute to the resonance. Total decay width in the multi-GeV range can arise from couplings involving the singlet and MSSM fields
