Extracting constraints from direct detection searches of supersymmetric dark matter in the light of null results from the LHC in the squark sector

TL;DR

This paper discusses how null results from LHC supersymmetry searches influence the interpretation of direct dark matter detection experiments, emphasizing the importance of correlated spin-dependent and spin-independent interactions.

Contribution

It redefines the framework for extracting constraints from direct detection by considering high-mass squark sectors, reducing free parameters, and highlighting the significance of SI and SD cross section correlations.

Findings

Squark sector at TeV scale simplifies constraint extraction.

Correlation between SI and SD cross sections is crucial for future detectors.

Null LHC results push supersymmetric models to higher mass scales.

Abstract

The comparison of the results of direct detection of Dark Matter, obtained with various target nuclei, requires model-dependent, or even arbitrary, assumptions. Indeed, to draw conclusions either the spin-dependent (SD) or the spin-independent (SI) interaction has to be neglected. In the light of the null results from supersymmetry searches at the LHC, the squark sector is pushed to high masses. We show that for a squark sector at the TeV scale, the framework used to extract contraints from direct detection searches can be redefined as the number of free parameters is reduced. Moreover, the correlation observed between SI and SD proton cross sections constitutes a key issue for the development of the next generation of Dark Matter detectors.
