Design of ALPHA Phase I: A Plasma Haloscope for 10--20 GHz Post-Inflation Axions
ALPHA Collaboration, Xiran Bai, Rustam Balafendiev +54
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…
DMRadio-Core: A new approach for GUT-scale axion searches
V. Ankel, C. Bartram, J. Begin +33
Searches for QCD axions with masses in the neV/ mass range are strongly motivated by new physics at the GUT scale and by well-motivated pre-inflationary axion symmetry breakin…
The Cryogenic System of DMRadio-50L
V. Ankel, C. Bartram, J. Begin +36
The DMRadio-50L experiment is designed to search for axion dark matter in the 5 kHz - 5 MHz frequency range using a lumped-element LC resonator and a toroidal magnet and to serve a…
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 Additionally, we present an analysis of an unpublished dataset covering a re…
Search for Double Beta Decays of Xe with EXO-200 Phase II
S. Al Kharusi, G. Anton, I. Badhrees +104
EXO-200 was a leading double beta decay experiment consisting of a single-phase, enriched liquid xenon time projection chamber filled with an admixture of 80.672% Xe and 19…
Dark Matter Axion Search with HAYSTAC Phase II
HAYSTAC Collaboration, Xiran Bai, M. J. Jewell +22
This Letter reports new results from the HAYSTAC experiment's search for dark matter axions in our galactic halo. It represents the widest search to date that utilizes squeezing to…
