Exploring neutrino loss with diffuse astrophysical neutrino fluxes
Ivan Esteban, Alberto M. Gago, M. C. Gonzalez-Garcia +1
We study the sensitivity of the diffuse high-energy neutrino flux observed in IceCube to new-physics effects resulting in an exponential flux attenuation along the trajectory, such…
Attenuation of the ultra-high-energy neutrino flux by dark matter scatterings
Ivan Esteban, Alejandro Ibarra
A flux of ultra-high-energy (UHE) neutrinos, produced by astrophysical sources at cosmological distances, is anticipated to exist and reach Earth. In this paper, we investigate the…
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…
Origin of cosmological neutrino mass bounds: background perturbations
Toni Bertólez-Martínez, Ivan Esteban, Rasmi Hajjar +2
The cosmological upper bound on the total neutrino mass is the dominant limit on this fundamental parameter. Recent observations-soon to be improved-have strongly tightened it, app…
New limits on neutrino decay from high-energy astrophysical neutrinos
Victor B. Valera, Damiano F. G. Fiorillo, Ivan Esteban +1
Since neutrinos have mass differences, they could decay into one another. But their lifetimes are likely long, even when shortened by new physics, so decay likely impacts neutrinos…
Detectable MeV Neutrino Signals from Neutron-Star Common-Envelope Systems
Ivan Esteban, John F. Beacom, Joachim Kopp
Common-envelope evolution - where a star is engulfed by a companion - is a critical but poorly understood step in, e.g., the formation pathways for gravitational-wave sources. Howe…
