Neutrino Floor in Isospin-Violating Dark Sector
摘要
The neutrino floor is a theoretical lower limit on DM-nucleon scattering cross section for a WIMP-like DM, which can be modified in a BSM setup. We work in an isospin violating (IV) dark sector, where both the dark matter and neutrino interaction can happen through IV interactions. In parts of the parameter space, we observe the neutrino goes down: i.e. more window for DM search. In other part of the parameter space, neutrino floor can be up, still allowing for the SM-like neutrino background.
