Gluino bounds: Simplified Models vs a Particular SO(10) Model (A Snowmass white paper)

TL;DR

This paper compares LHC gluino bounds derived from simplified models with those from a specific SO(10) grand unified theory, highlighting differences in search sensitivities due to varying final state signatures.

Contribution

It reinterprets LHC results within a particular SO(10) model, demonstrating how non-simplified topologies affect gluino mass bounds compared to simplified models.

Findings

Bounds are weaker for the SO(10) model due to fewer b-jets.

Hadronic searches optimized for simplified models are less sensitive to the specific SO(10) topology.

Fewer b-jets in the model reduce the effectiveness of standard search strategies.

Abstract

We consider the results from the first run of LHC studied in the context of simplified models and re-interpret them for a particular SO(10) model with a non-simplified topology. Hadronic searches have been designed to obtain the best sensitivity for the simplified models. They require multiple b-jets in the final state. But we show that the bounds obtained from these searches are weaker in the case of the particular model studied here, since there are fewer b-jets.
