Constraining the Selectron Mass in the Process e^- + gamma --> neutralino_1 +selectron_{L/R}^- --> e^- + 2 neutralino_1

TL;DR

This paper explores how the process involving electron-photon collisions can set bounds on selectron masses beyond traditional collider limits and tests the underlying theoretical mass relations.

Contribution

It introduces a method to constrain selectron masses above pair production thresholds using electron-photon interactions and examines testing renormalization group equations.

Findings

Selectron masses can be constrained beyond pair production kinematic limits.

The process allows testing of renormalization group equations for selectron masses.

Potential to improve bounds on supersymmetric particle masses.

Abstract

With the process $e^-\gamma \to \tilde{\chi}_1^0 \tilde{e}_{L/R}^- \to e^- \tilde{\chi}_1^0 \tilde{\chi}_1^0$ it is possible to constrain selectron masses above the kinematical limit of the pair production process in $e^+e^-$ colliders. We investigate these mass ranges and discuss the possibility to test the renormalization group equations for the selectron masses.
