TL;DR

This paper explores R-parity violating supersymmetry models with specific operators, analyzing their detectability at the LHC and proposing improved search strategies to uncover challenging scenarios.

Contribution

It introduces a new class of R-parity violating SUSY models with specific operators and assesses their testability at current and future LHC runs.

Findings

Most challenging scenarios can be probed at 14 TeV LHC with 300 fb$^{-1}$

Certain sbottom-Bino scenarios remain difficult to detect

Enhanced search strategies using multiple b-jets are promising

Abstract

The strong constraints on the R-parity conserving supersymmetry (SUSY) from the LHC searches motivate us to consider the new models in which the low-scale SUSY is still allowed. We propose a kind of R-parity violating SUSY scenarios with a non-zero $U^c_2 D^c_2 D^c_3$ operator. Three relevant LHC searches are recasted to test the status of this scenario in terms of four simplified models, with either light stop-Bino, stop-Higgsino, sbottom-Bino or sbottom-Higgsino. Some difficult scenarios for the LHC SUSY searches in these simplified models are identified. By extrapolate the current LHC searches to the future 14 TeV LHC with integrated luminosity of 300 fb$^{-1}$, most of the difficult scenarios can be probed, except the sbottom-Bino simplified one. An improved search, which utilises the multiple b-jets as well as its kinematic features, is expected to probe the signature of this case.
