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…
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 Additionally, we present an analysis of an unpublished dataset covering a re…
A Beamdump Facility at Jefferson Lab
Patrick Achenbach, Andrei Afanasev, Pawel Ambrozewicz +47
This White Paper is exploring the potential of intense secondary muon, neutrino, and (hypothetical) light dark matter beams produced in interactions of high-intensity electron beam…
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…
