The Physics Case for Axions, WIMPs, WISPs and Other Weird Stuff

TL;DR

This paper advocates for the pursuit of experimental searches for axions, WIMPs, WISPs, and similar phenomena, emphasizing their strong theoretical and observational motivations in low-energy physics.

Contribution

It articulates a compelling physics case for exploring these particles, integrating experimental, observational, and theoretical motivations.

Findings

Strong experimental and observational evidence supports search efforts.

Testing these particles can validate or challenge current theoretical models.

Low-energy experiments are crucial for discovering new fundamental physics.

Abstract

We argue that there exists an excellent `physics case' motivating the search for axions, WIMPs, WISPs and other phenomena testable at low energies. This physics case arises from both experimental and observational evidence as well as the desire to test theoretical model building.
