TL;DR
This paper models the Galactic neutrino background resulting from cosmic ray interactions with the interstellar medium, considering various cosmic ray nuclei and their contribution to neutrino flux.
Contribution
It introduces a diffusive model for cosmic ray propagation that estimates neutrino flux from multiple cosmic ray nuclei interactions with the ISM.
Findings
Estimated neutrino flux from cosmic ray interactions with ISM.
Quantified contributions of different cosmic ray nuclei to neutrino production.
Provided a framework for predicting Galactic neutrino background.
Abstract
We use a diffusive model for the propagation of Galactic cosmic rays to estimate the charged pion production in interactions with protons of the interstellar medium. Cosmic ray nuclei from proton to iron are considered and the corresponding contribution to the neutrino secondary flux produced as a result of spallation is also estimated.
