Resonant heterodyne conversion applied to a low-frequency haloscope for dark matter axion searches in the 1-35 MHz range

Jose R. Navarro-Madrid, José Reina-Valero, Alejandro Díaz-Morcillo +1

We study resonant heterodyne up-conversion in the RADES-BabyIAXO haloscope as a method to search for low-mass dark matter axions using microwave cavities. Starting from axion elect…

A study of multicavity concept applied to hexagonal coaxial haloscopes

J. M. García-Barceló, Jose R. Navarro-Madrid, Alejandro Díaz-Morcillo

In this work, a study on the development of scalable multicavity architectures for axion haloscopes, based on a hexagonal coaxial geometry operating at GHz frequencies, is pre…

RADES axion search results with a High-Temperature Superconducting cavity in an 11.7 T magnet

S. Ahyoune, A. Álvarez Melcón, S. Arguedas Cuendis +23

We describe the results of a haloscope axion search performed with an 11.7 T dipole magnet at CERN. The search used a custom-made radio-frequency cavity coated with high-temperatur…

Enhancement of dark-photon haloscope sensitivity with degenerate modes: toward axion-level form factor and polarization determination

Jose R. Navarro-Madrid, José Reina-Valero, Alejandro Díaz-Morcillo +1

The dark photon has been postulated as a potential constituent of dark matter, exhibiting notable similarities to the axion. The primary distinction between the two particles lies…

The International Axion Observatory (IAXO): case, status and plans. Input to the European Strategy for Particle Physics

A. Arcusa, S. Ahyoune, K. Altenmuller +120

The International Axion Observatory (IAXO) is a next-generation axion helioscope designed to search for solar axions with unprecedented sensitivity. IAXO holds a unique position in…
