First characterisation of the MAGO cavity, a superconducting RF detector for kHz–MHz gravitational waves Open
Heterodyne detection using microwave cavities is a promising method for detecting high-frequency gravitational waves (GWs) or ultralight axion dark matter. In this work, we report on studies conducted on a spherical 2-cell cavity developed…

Probes of CP-violating Higgs couplings and their impact on baryogenesis Open
We investigate the CP structure of the Higgs couplings to fermions and gluons by using constraints from LHC measurements and the electric dipole moment of the electron. We further use these constraints to assess how much of the observed ba…
