Probing HNL-ALP couplings at colliders
Arturo de Giorgi, Luca Merlo, Jean-Loup Tastet
Axion-like particles (ALPs) and heavy neutral leptons (HNLs) are both well-motivated extensions of the Standard Model. As ALPs couple to on-shell fermions proportionally to their m…
The Low-Scale Seesaw Solution to the and Anomalies
Arturo de Giorgi, Luca Merlo, Stefan Pokorski
The recent CDF-II measurement of the -boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the contex…
The cost of an ALP solution to the neutral -anomalies
J. Bonilla, A. de Giorgi, B. Gavela +2
The neutral anomalies in decays are analysed in terms of the tree-level exchange of an axion-like-particle (ALP), within the effective field theory framework. The complete two-…
Warm dark matter from a gravitational freeze-in in extra dimensions
Arturo de Giorgi, Stefan Vogl
We study the freeze-in of gravitationally interacting dark matter in extra dimensions. Focusing on a minimal dark matter candidate that only interacts with the SM via gravity in a…
