LHC Signatures Of Scalar Dark Energy

TL;DR

This paper explores how scalar dark energy fields interacting with the Standard Model could produce detectable signals at the LHC, such as top-antitop plus missing energy and mono-jet events, and discusses distinguishing these from dark matter signals.

Contribution

It introduces LHC signatures specific to scalar dark energy fields and analyzes their potential observability and differentiation from dark matter signals.

Findings

tar t + missing energy signals are promising probes

Mono-jet searches can detect scalar dark energy

Potential to distinguish dark energy from dark matter signatures

Abstract

Scalar dark energy fields that couple to the Standard Model can give rise to observable signatures at the LHC. In this work we show that $t\bar t+$missing energy and mono-jet searches are suitable probes in the limit where the dark energy scalar is stable on collider distances. We discuss the prospects of distinguishing the dark energy character of new physics signals from dark matter signatures and the possibility of probing the self-interactions of the dark energy sector.
