On sgoldstino interpretation of the diphoton excess

TL;DR

The paper proposes that the 750 GeV diphoton excess observed at the LHC can be explained by a sgoldstino particle in low-scale supersymmetry breaking models, with testable phenomenological signatures.

Contribution

It introduces the sgoldstino as a natural candidate for the diphoton excess within supersymmetric models, providing a new interpretation and phenomenological implications.

Findings

Sgoldstino can account for the 750 GeV diphoton excess

Phenomenological signatures consistent with current LHC data

Testable predictions for future collider experiments

Abstract

We point out that the diphoton excess at about 750 GeV recently discovered by the LHC experiments can be explained within supersymmetric models with low scale supersymmetry breaking with sgoldstino as a natural candidate. We discuss phenomenological consequences of this scenario describing possible signatures to test this hypothesis.
