Perspectives on the detection of supersymmetric Dark Matter

TL;DR

This paper reviews the current status of Dark Matter detection efforts, examining supersymmetry as a paradigm, comparing predicted detection signals with observations, and discussing debated signals like positron and Fermi GeV excesses.

Contribution

It provides a comprehensive overview of supersymmetric Dark Matter detection prospects, analyzing recent experimental results and theoretical predictions in the context of cosmology and particle physics.

Findings

Current detection methods have not confirmed Dark Matter signals.

Supersymmetry offers a compelling framework but faces challenges from null results.

Debated signals like positron and Fermi GeV excesses are incompatible and may have astrophysical explanations.

Abstract

Up to now searches for Dark Matter (DM) detection have not been successful, either because our paradigm in how DM signals should look like are wrong or the detector sensitivity is still too low in spite of the large progress made in recent years. We discuss both possibilities starting with what we know about DM from cosmology and why Supersymmetry provides such an interesting paradigm for cosmology and particle physics in order to appreciate what it means to give up this paradigm. In addition, we compare the predicted cross sections for direct and indirect DM detection with observations with emphasis on the latest developments. Especially, we discuss the possible origins of the two hotly debated candidates for a DM annihilation signal, namely the positron excess and the Fermi GeV excess, which are unfortunately incompatible with each other and more mundane astrophysical explanations exist.
