Probing the Majorana Nature and CP Properties of Neutralinos

TL;DR

This paper proposes two effective methods to investigate whether neutralinos are Majorana particles and to explore their CP violation characteristics at future electron-positron colliders.

Contribution

It introduces novel, straightforward techniques for testing the Majorana nature and CP properties of neutralinos in collider experiments.

Findings

Methods effectively distinguish Majorana from Dirac neutralinos.

Techniques can detect CP violation in neutralino interactions.

Applicable to future $e^+e^-$ collider experiments.

Abstract

Two powerful and straightforward methods are presented for probing the Majorana nature and CP violation of neutralinos at future $e^+e^-$ linear colliders.
