Searching for WISPy Cold Dark Matter with a Dish Antenna

TL;DR

This paper proposes a broadband dish antenna technique to search for WISPy cold dark matter, such as hidden photons and axion-like particles, covering a wide mass range in a single measurement.

Contribution

Introduction of a novel broadband dish antenna method for detecting WISPs as dark matter candidates, enabling efficient mass range exploration.

Findings

Technique is broadband, covering a wide mass range.

Allows single-measurement exploration of multiple WISP masses.

Potentially improves sensitivity to WISP dark matter detection.

Abstract

The cold dark matter of the Universe may be comprised of very light and very weakly interacting particles, so-called WISPs. Two prominent examples are hidden photons and axion-like particles. In this note we propose a new technique to sensitively search for this type of dark matter with dish antennas. The technique is broadband and allows to explore a whole range of masses in a single measurement.
