Dirac-Phase CP-Violation in the Low-Scale Type-I Seesaw with Three Right-Handed Neutrinos

Alessandro Granelli, Juraj Klarić, S. T. Petcov

We study the low-scale type-I seesaw with three right-handed neutrinos (i.e. heavy Majorana neutrinos) when the CP-violation arises solely from the low-energy Dirac phase of t…

Dark Matter Interpretation of the Super-Kamiokande Antineutrino Excess and Predictions for JUNO

Alessandro Granelli, Silvia Pascoli, Salvador Rosauro-Alcaraz

Super-Kamiokande has reported a small excess of electron antineutrino events in the 20 MeV energy range, in the search for the diffuse supernova neutrino background. We interpret t…

ULYSSES the Third: An Odyssey Towards a Unified Python Toolkit for Leptogenesis

Alessandro Granelli, Juraj Klarić, Dhruv Pasari +2

We present the third release of , a Python package for the numerical evaluation of the baryon asymmetry generated through leptogenesis. This version includes code…

Diffuse astrophysical neutrinos from dark matter around blazars

Andrea Giovanni De Marchi, Alessandro Granelli, Jacopo Nava +1

Neutrinos from blazars can originate from inelastic scatterings between protons within their jets and sub-GeV dark matter (DM) around them, explaining IceCube detections of neutrin…

Boosted dark matter versus dark matter-induced neutrinos from single and stacked blazars

Andrea Giovanni De Marchi, Alessandro Granelli, Jacopo Nava +1

The physics responsible for the production of observed high-energy neutrinos have not been established so far, neither for the diffuse astrophysical ones nor for those detected fro…

Did IceCube discover Dark Matter around Blazars?

Andrea Giovanni De Marchi, Alessandro Granelli, Jacopo Nava +1

Models of blazar jets, that explain observations of their photon spectra, typically predict too few neutrinos to be possibly seen by existing telescopes. In particular, they fall s…
