Multi-hadron final states in RPV supersymmetric models with extra matters

TL;DR

This paper explores how adding extra matter in RPV supersymmetric models can relax gluino mass constraints at the LHC by affecting decay signatures and detection sensitivities.

Contribution

It introduces the impact of extra matter on gluino decay chains in RPV SUSY models and analyzes how this affects experimental search sensitivities.

Findings

Extra matter can relax gluino mass limits in RPV models.

Increased decay products lead to softer jets, complicating detection.

Combined search strategies improve sensitivity to these scenarios.

Abstract

The gluino mass has been constrained by various search channels at the LHC experiments and the recent analyses are even sensitive to the cases where gluinos decay to quarks at the end of the decay chains through the baryonic RPV operator. We argue that introduction of extra matters, which is partly motivated by cancelling anomalies of discrete R symmetry, may help to relax the gluino mass limit when the RPV hadronic gluino decays are considered. In the scenarios where the extra matter states appear in the gluino decay chains, the number of decay products increases and each jet becomes soft, making it difficult to distinguish the signal from backgrounds. We investigate the sensitivity of existing analyses to such scenarios and demonstrate that the gluino mass limit can be relaxed if the mass spectrum reconciles the sensitivities of high $p_T$ jet searches and large jet multiplicity searches.
