Cryogenic RF characterization of the MAGO cavity for high-frequency gravitational-wave detection
Can Dokuyucu, Bianca Giaccone, Tom Krokotsch +13
Superconducting radio-frequency (SRF) cavities are promising resonant sensors for gravitational-wave detection in the kHz-MHz frequency range. We report the cryogenic RF characteri…
BSM Searches at a Photon Collider with Energy GeV
Marten Berger, Gudrid Moortgat-Pick
The possibility of a photon collider extension to the beam dump of the GeV European XFEL has already been discussed before as the first high energy collider of its sort. It…
CP-violation and its implications in a complex singlet extension of 2HDM
Jayita Lahiri, Gudrid Moortgat-Pick
We investigate CP-violation in the complex singlet extension of the general Two Higgs Doublet Model (2HDM) with Yukawa alignment condition. We first explore the possibility of expl…
Covariant eigenmode overlap formalism for gravitational wave signals in electromagnetic cavities
Jordan Gué, Tom Krokotsch, Gudrid Moortgat-Pick
We develop a coordinate invariant formalism which describes the mechanical and electromagnetic interaction of gravitational waves (GWs) with a wide class of resonant detectors. We…
Laboratory Frame Representation for General High-Frequency Gravitational Waveforms
Lars Fischer, Tom Krokotsch, Gudrid Moortgat-Pick
Next-generation gravitational wave (GW) experiments will explore higher frequency ranges, where GW wavelengths approach the size of the detector itself. In this regime, GWs may be…
First characterisation of the MAGO cavity, a superconducting RF detector for kHz-MHz gravitational waves
Lars Fischer, Bianca Giaccone, Ivan Gonin +12
Heterodyne detection using microwave cavities is a promising method for detecting high-frequency gravitational waves or ultralight axion dark matter. In this work, we report on stu…
