Particle Physics Prospects of High Frequency Gravitational Wave Detection — •Tom Krokotsch¹, Lars Fischer¹, Gudrid Moortgat-Pick^1,2, Michel Paulsen¹, Krisztian Peters², and Marc Wenskat¹ — ¹Universität Hamburg, Hamburg, Germany — ²Deutsches Elektronen Synchrotron DESY, Hamburg, Germany

Gravitational wave searches so far have mainly focused on frequencies lower than kHz. However, expanding the search to higher frequencies will open an entirely new window for physics beyond the standard model and dark matter research.

Electromagnetic cavities are particularly sensitive to mechanical deformations caused by gravitational waves in the kHz to MHz regime. A detector based on this concept could search for primordial black holes as dark matter candidates or for novel scalar bosons like axions through the effect of black hole superradiance. Additionally, new exclusion limits could be set on further non-coherent gravitational wave sources.

The aim of this talk is to make a case for high frequency gravitational wave detection with superconducting radio frequency cavities and highlight the opportunities it brings for future particle physics.
