Axion-like Particles from Hypernovae
Andrea Caputo, Pierluca Carenza, Giuseppe Lucente +5
It was recently pointed out that very energetic subclasses of supernovae (SNe), like hypernovae and superluminous SNe, might host ultra-strong magnetic fields in their core. Such f…
Detecting the radiative decay of the cosmic neutrino background with line-intensity mapping
José Luis Bernal, Andrea Caputo, Francisco Villaescusa-Navarro +1
We study the possibility to use line-intensity mapping (LIM) to seek photons from the radiative decay of neutrinos in the cosmic neutrino background. The Standard Model prediction…
Directional detection of light dark matter from three-phonon events in superfluid He
Andrea Caputo, Angelo Esposito, Fulvio Piccinini +2
We present the analysis of a new signature for light dark matter detection with superfluid He: the emission of three phonons. We show that, in a region of mass below the MeV, t…
The see-saw portal at future Higgs Factories
Daniele Barducci, Enrico Bertuzzo, Andrea Caputo +2
We consider an extension of the Standard Model with two right-handed singlet fermions with mass at the electroweak scale that induce neutrino masses, plus a generic new physics sec…
Revisiting longitudinal plasmon-axion conversion in external magnetic fields
Andrea Caputo, Alexander J. Millar, Edoardo Vitagliano
In the presence of an external magnetic field the axion and the photon mix. In particular, the dispersion relation of a longitudinal plasmon always crosses the dispersion relation…
Minimal flavor violation in the see-saw portal
Daniele Barducci, Enrico Bertuzzo, Andrea Caputo +1
We consider an extension of the Standard Model with two singlet leptons, with masses in the electroweak range, that induce neutrino masses via the see-saw mechanism, plus a generic…
