T.Wuensch, W.RADES axion search results with a high-temperature superconducting cavity in an 11.7 T magnetART-2025-144070We describe the results of a haloscope axion search performed with an 11.7 T dipole magnet at CERN. The search used a custom-made radio-frequency cavity coated with high-temperature superconducting tape. A set of 27 h of data at a resonant frequency of around 8.84 GHz was analysed. In the range of axion mass 36.5676 μeV to 36.5699 μeV, corresponding to a width of 554 kHz, no signal excess hinting at an axion-like particle was found. Correspondingly, in this mass range, a limit on the axion to photon coupling-strength was set in the range between gaγ ≳ 6.3 × 10−13 GeV−1 and gaγ ≳ 1.59 × 10−13 GeV−1 with a 95% confidence level.2025http://zaguan.unizar.es/record/16087910.1007/JHEP04(2025)113http://zaguan.unizar.es/record/160879oai:zaguan.unizar.es:160879info:eu-repo/grantAgreement/ES/AEI/CEX2019-000918-Minfo:eu-repo/grantAgreement/EUR/ERC-2017-AdG-788781info:eu-repo/grantAgreement/EUR/ERC-2018-StG-802836-AxScaleinfo:eu-repo/grantAgreement/EC/H2020/730871/EU/Accelerator Research and Innovation for European Science and Society/ARIESThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 730871-ARIESinfo:eu-repo/grantAgreement/ES/MICINN/PID2019-108122GB-C32info:eu-repo/grantAgreement/ES/MICINN/PID2019-108122GB-C33Journal of High Energy Physics 113 (2025), [23 pp.]byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
