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…
