Consequences of Modified Cosmologies in DM abundance and PeV IceCube signals
Abstract
To explain the high-energy astrophysical neutrino flux with energies $\sim PeV$ recently observed by IceCube collaboration and the relic abundance of DM in the Universe, we consider the minimal 4-dimensional operator $\sim y_{αχ}\overline{L_{L_α}}\, H\, χ$. The cosmological background is assumed to evolve according to $f({\cal T})$ cosmology, where ${\cal T}$ is the scalar torsion.
