Findings

Three-photon search strategy outperforms two-photon methods in certain parameter regions.

New constraints on supersymmetric models are established using the proposed method.

The study provides a framework for future collider searches for complex supersymmetric signatures.

Abstract

This paper discusses electroweak collider signatures of the NMSSM with multiple-sector gauge mediation. We focus on the production of neutralinos and charginos which cascade decay into standard model particles and lighter supersymmetric particles, with special emphasis on final states with multiple photons. A search strategy for signatures with at least three photons is presented and compared with current exclusion limits based on two-photon searches. We show that in many regions of the parameter space our strategy gives stronger constraints than the existing two-photon analysis for these models.
