Probing Neutrinophilic Axion-Like Particles in Tritium Beta Decay
Yi Chung, Florian Goertz, Maya Hager +1
We investigate the prospects for constraining neutrinophilic axion-like particles via measurements of the tritium beta decay spectrum, as performed by the KATRIN experiment and its…

Characterizing LHC-Resonances in extended HEFT: information on the nature of extended scalar sectors
Giorgio Arcadi, David Cabo-Almeida, Florian Goertz +1
In theories with extended scalar sectors the lightest new scalar degree of freedom might be accessible at colliders. Going beyond simplified models, such a theory can be described…

Phasing out of Darkness: From Sterile Neutrino Dark Matter to Neutrino Masses via Time-Dependent Mixing
Florian Goertz, Maya Hager, Giorgio Laverda +1
Sterile neutrinos are a compelling candidate for generating neutrino masses and for elucidating the nature of dark matter. Astrophysical X-ray constraints on sterile neutrino dark…
