Constraining Higgsino Kink Tracks from Existing LHC Searches

TL;DR

This paper explores how long-lived charged Higgsinos could produce detectable kink signals at the LHC, analyzing existing searches to constrain and characterize these signals within supersymmetric models.

Contribution

It introduces a method to identify Higgsino kink signals in LHC data and compares them to other long-lived particle signatures, providing new constraints on Higgsino properties.

Findings

Higgsino kink signals can be constrained by existing LHC searches.

Higgsino kink tracks have distinct kinematic features from Wino and slepton tracks.

The study offers a way to infer Higgsino model parameters from observed kink signals.

Abstract

Considering the supersymmetric model with the long-lived charged Higgsino, we discuss how Higgsino kink signals can show up in the latest LHC Disappearing Track (DT) and stable chargino searches. We derive constraints on the Higgsino kink signal, and characterize it in comparison to the Wino DT and the slepton kink track. We also discuss how to infer Higgsino model kinematics.
