PY - 2024 DA - 2024// TI - Symmetries and selection rules: optimising axion haloscopes for Gravitational Wave searches T2 - J. High Energy Phys. JO - Journal of High Energy Physics SP - 128 EP - 51pp VL - 03 IS - 3 PB - Springer KW - Axions and ALPs KW - Early Universe Particle Physics AB - In the presence of electromagnetic fields, both axions and gravitational waves (GWs) induce oscillating magnetic fields: a potentially detectable fingerprint of their presence. We demonstrate that the response is largely dictated by the symmetries of the instruments used to search for it. Focussing on low mass axion haloscopes, we derive selection rules that determine the parametric sensitivity of different detector geometries to axions and GWs, and which further reveal how to optimise the experimental geometry to maximise both signals. The formalism allows us to forecast the optimal sensitivity to GWs in the range of 100 kHz to 100 MHz for instruments such as ABRACADABRA, BASE, ADMX SLIC, SHAFT, WISPLC, and DMRadio.
