Design of ALPHA Phase I: A Plasma Haloscope for 10--20 GHz Post-Inflation Axions
ALPHA Collaboration, Xiran Bai, Rustam Balafendiev +53
The axion is a well-motivated hypothetical particle capable of resolving both the strong CP problem and the dark matter mystery, with recent post-inflationary cosmological simulati…
Search for Dark Photons between 16.96--19.52 eV with the HAYSTAC Experiment
Xiran Bai, A. Droster, J. Echevers +21
We report dark photon results from HAYSTAC Phase II using data from previously reported axion searches. Additionally, we present an analysis of an unpublished dataset covering a re…
Practical photonic band gap structures for high frequency axion haloscopes
D. Goulart, A. M. Sindhwad, H. M. Jackson +7
Current and future searches for dark matter axions, based on their resonant conversion to photons in a magnetic field, span many orders of magnitude. A major impediment to designin…
Benchmarking the design of the cryogenics system for the underground argon in DarkSide-20k
20k Collaboration, F. Acerbi, P. Adhikari +315
DarkSide-20k (DS-20k) is a dark matter detection experiment under construction at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. It utilises ~100 t of low radioactivity a…
A tunable photonic band gap resonator for axion dark matter searches
Samantha M. Lewis, Dillon T. Goulart, Mirelys Carcana Barbosa +5
Axions are a well-motivated dark matter candidate particle. Haloscopes aim to detect axions in the galactic halo by measuring the photon signal resulting from axions interacting wi…
DarkSide-20k sensitivity to light dark matter particles
20k Collaboration, F. Acerbi, P. Adhikari +310
The dual-phase liquid argon time projection chamber is presently one of the leading technologies to search for dark matter particles with masses below 10 GeV/c. This was demons…
