Does the LHC exclude SUSY Particles at the ILC?

TL;DR

This paper reevaluates LHC exclusion limits on SUSY particles, considering a specific decay mode, revealing a larger viable parameter space for electroweak SUSY particles accessible at the ILC.

Contribution

It incorporates a full one-loop calculation of a decay mode, showing that previous exclusions are significantly weakened, expanding the potential for SUSY detection at future colliders.

Findings

Including the neu2 -> neu1 h decay reduces LHC exclusion limits.

A large parameter space remains for electroweak SUSY particles.

Electroweak SUSY particles can be produced at the ILC.

Abstract

We analyze the LHC SUSY 1exclusion limits in the cha1-neu2 channel. We take into account the decay neu2 -> neu1 h (based on a full one-loop calculation in the complex MSSM), which has a non-negligible branching ratio. Including this decay strongly reduces the excluded parameter space in the m_neu2-m_neu1 plane. This opens up a large parameter space for electroweak SUSY particles, easily allowing the production of these particles at the ILC.
