Electroweak Precision Constraints on Dark Photon Models with Generalized Mixing
Enrico Bertuzzo, Csaba Csaki, Fernanda Huller
We present a global fit to electroweak precision observables (EWPOs) in dark photon (DP) models containing both kinetic and mass mixing between the DP and the neutral gauge bosons…
Two portals to GeV sterile neutrinos : dipole versus mixing
Enrico Bertuzzo, Michele Frigerio
Massive sterile neutrinos, also known as heavy neutral leptons, can have a mixing with active neutrinos, , as well as a dipole coupling to the photon, . We study the interpla…
Illuminating the dark: mono- signals at NA62
D. Barducci, E. Bertuzzo, M. Taoso +2
Dipole interactions between dark sector states or between a Standard Model particle and a dark state can efficiently be searched for via high-intensity fixed-target facilities. We…
Complex Dark Photon Dark Matter EFT
Enrico Bertuzzo, Tommaso Sassi, Andrea Tesi
We construct an effective field theory for complex Stueckelberg dark photon dark matter. Such an effective construction can be realized by writing down a complete set of operators…
Gravitationally produced Dark Matter and primordial black holes
Enrico Bertuzzo, Yuber F. Perez-Gonzalez, Gabriel M. Salla +1
We examine how the existence of a population of primordial black holes (PBHs) influences cosmological gravitational particle production (CGPP) for spin-0 and spin-1 particles. In a…
ALPs, the on-shell way
Enrico Bertuzzo, Christophe Grojean, Gabriel M. Salla
We study how the coupling between axion-like particles (ALPs) and matter can be obtained at the level of on-shell scattering amplitudes. We identify three conditions that allow us…
