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…
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…
From oversimplified to overlooked: the case for exploring Rich Dark Sectors
Asli Abdullahi, Francesco Costa, Andrea Giovanni De Marchi +9
The Standard Model (SM) of particle physics provides a very successful description of fundamental particles and their interactions but it is incomplete, as neutrino masses, dark ma…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-Martínez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
Insights on the Scale of Leptogenesis from Neutrino Masses and Neutrinoless Double-Beta Decay
Alessandro Granelli, Koichi Hamaguchi, Maura E. Ramirez-Quezada +3
We revisit the thermal leptogenesis scenario in the type-I seesaw framework featuring three heavy Majorana neutrinos with a hierarchical mass spectrum. We focus on low energy obser…
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…
