Large Jet Multiplicities and Natural Supersymmetry at the LHC

TL;DR

This paper proposes a new search strategy for detecting natural supersymmetry at the LHC by focusing on events with many jets and missing energy, which is effective even without charged leptons.

Contribution

It introduces a novel jet-based search approach for supersymmetry that does not rely on charged leptons or b-tagging, broadening detection possibilities.

Findings

Strategy is effective for models with light gluino, stop, and neutralino.

Performance is comparable or superior to traditional lepton-based methods.

Applicable to a wide class of models involving dark matter and top quarks.

Abstract

We consider a search strategy for new physics at the Large Hadron Collider which focuses on the signature of many jets and missing transverse energy, but no charged leptons. We show that this signature can be useful in probing a wide class of models, including natural supersymmetry, in which dark matter is produced in conjunction top quarks. As an example, we apply this strategy to a simplified supersymmetric model with a light gluino, light stop and light neutralino. The efficacy of this strategy is comparable to (and in some cases better than) that of other strategies which require charged leptons and/or b-tagged jets.
