Natural SUSY: LHC and Dark Matter direct detection experiments interplay

TL;DR

This paper investigates how natural supersymmetry scenarios with higgsino-like dark matter can be tested at the 13 TeV LHC through monojet searches, considering systematic uncertainties and the interplay with direct detection experiments.

Contribution

It provides a detailed analysis of the LHC's potential to probe natural SUSY with higgsino dark matter and explores the complementarity with direct detection experiments.

Findings

LHC monojet searches can effectively probe natural SUSY scenarios.

Systematic uncertainties significantly impact the search sensitivity.

Combining collider and direct detection data enhances discovery prospects.

Abstract

Natural SUSY scenarios with a low value of the $\mu$ parameter, are characterised by a higgsino-like dark matter candidate, and a compressed spectrum for the lightest higgsinos. We explore the prospects for probing this scenario at the 13 TeV stage of the LHC via monojet searches, with various integrated luminosity options, and demonstrate how these results are affect by different assumptions on the achievable level of control on the experimental systematic uncertainties. The complementarity between collider and direct detection experiments (present and future) is also highlighted.
