Description
In ΛCDM cosmology, Dark Matter (DM) and neutrinos are assumed to be non-
interacting. However, several BSM scenarios require DM-neutrino interaction, leading to
DM-neutrino scattering and annihilation of DM into neutrinos. We investigate this scenario
by analysing the PLANCK-2018 and BOSS-BAO 2014 dataset and constrain strength of such
interactions. We also discuss a particle DM model which gives rise to such viable processes,
we then map the constraints to the parameter space of the model.
