Evidence for parity violation in gravitational fields
V. Gharibyan, V. Adler, P. D. Allfrey +28
Discrete symmetries in gravity have only been tested for low energy, non-relativistic matter, confirming the perfectly symmetric general relativity. A hint for high energy $\cal{CP…
Any Light Particle Searches with ALPS II: first science results
Daniel C. Brotherton, Zachary R. Bush, Sandy Croatto +37
The light-shining-through-a-wall experiment ALPS II at DESY in Hamburg searched for axions and similar lightweight particles in its first science campaign from February to May 2024…
Sensitivity of a closed dielectric haloscope to axion dark matter
A. Ivanov, D. Leppla-Weber, B. Ary dos Santos Garcia +40
We present a method to determine the sensitivity of a closed dielectric haloscope to axion dark matter. Dielectric haloscopes aim to probe the theoretically well-motivated axion ma…
Design and construction of a cryogenic subcooler-box for supplying single phase supercritical helium to dark matter and gravitational wave experiments
Udai Raj Singh, Rajinikumar Ramalingam, Christoph Reinhardt +4
We report on the design, development, and installation of the ALPS Cryo-Platform Subcooler Box (ACPS), which is part of the cryogenic platform being established in the HERA North H…
First search for axion dark matter with a Madmax prototype
B. Ary dos Santos Garcia, D. Bergermann, A. Caldwell +34
This paper presents the first search for dark matter axions with mass in the ranges 76.56 to 76.82 eV and 79.31 to 79.53 eV using a prototype setup for the MAgnetized Disk…
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…
