| contents | The absence of definitive results for WIMP dark matter has sparked growing interest in alternative dark matter candidates, such as axions and Axion-Like Particles (ALPs), which also provide insight into the strong CP problem. The Mitchell Institute Neutrino Experiment at Reactor (MINER), conducted at the Nuclear Science Center of Texas A&M University, investigated ALPs near a 1 MW TRIGA nuclear reactor core, positioned approximately 4 meters away. This experiment employed cryogenic sapphire detectors with a low detection threshold (approximately 100 eV), equipped with a Transition Edge Sensor capable of detecting athermal phonons. Due to the low-background environment, we were able to exclude ALPs with axion-photon coupling and axion-electron coupling as small as \(g_{aγγ} = 10^{-5}\) and \(g_{aee} = 10^{-7}\), respectively. Energy depositions below 3 keV were not considered and remain blinded for our Coherent Elastic Neutrino Nucleus Scattering (CEvNS) analysis. This is the first result demonstrating the MINER experiment's potential to probe low-mass ALPs, enabled by its low-threshold detector and proximity to a reactor. |
