Description

As an extension of our previous work on the Diffuse Boosted Cosmic Neutrino Background, we further incorporate charged current processes and deep inelastic scattering. We found that deep inelastic scattering significantly enhances the boosted flux at high energies, and that IceCube already places an upper limit on the $C\nu B$ overdensity of $\sim O(10^2) - O(10^3)$. Furthermore, the combination of 10 future neutrino telescopes with similar sensitivity to IceCube-Gen2 will allow us to test the $\Lambda$CDM expected $C\nu B$ density for a lightest neutrino mass $\sim 0.1\mathrm{eV} - 0.2 \mathrm{eV}$.
