# Searching for Axino-Like Particle at Fixed Target Experiments

## TL;DR

This paper explores the potential for fixed target experiments to detect axino-like particles, a dark matter candidate, by analyzing neutralino production and decay signatures.

## Contribution

It provides a detailed calculation of neutralino production and decay rates, proposing a new experimental approach to search for axino-like particles.

## Key findings

- Predicted detectable signals in fixed target experiments
- Estimated event rates for neutralino decay products
- Highlighted the viability of using decay signatures to identify axino-like particles

## Abstract

We investigate the detectability of axino-like particle, which is defined as a supersymmetric partner of axion-like particle and can be a good candidate for dark matter in our Universe. Especially, we consider the fixed target experiments to search for the light axino-like particle with a neutralino as the next-to-lightest supersymmetric particle. We calculate the production and decay rate of neutralinos and the consequent number of events (such as photons and charged leptons) that are produced when the neutralinos decay to the axino-like particles.
