TL;DR

This paper explores the potential of future 100 TeV colliders and direct detection experiments to discover or constrain split supersymmetry models, especially focusing on electroweakino mass reach and dark matter implications.

Contribution

It analyzes the collider and direct detection sensitivities for electroweakinos in split supersymmetry scenarios, highlighting the complementarity of these approaches.

Findings

A 100 TeV collider can reach electroweakino masses up to 3 TeV.

Long-lived Winos in anomaly mediation can be probed at future colliders.

Combined collider and direct detection efforts can cover large parameter space.

Abstract

We studied the interplay between the mass reach for electroweakinos at future hadron colliders and direct detection experiments. The lack of new phenomena at the LCH motivates us to focus on split supersymmetry scenarios with different electroweakino spectra. A 100 TeV hadron collider may reach masses up to 3 TeV in models of anomaly mediation with long-lived thermal Winos. Moreover, in scenarios where the lightest neutralino is not the only dark matter component, the interplay between collider searches and direct detection experiments might cover large part of the parameter space.
