Findings

IVDM models alter the neutrino background depending on target material.

Certain IVDM configurations can reduce the neutrino fog impact.

The study offers strategies to mitigate neutrino background in specific scenarios.

Abstract

First observation of solar neutrinos through coherent elastic neutrino-nucleus scattering by dark matter (DM) direct detection (DD) experiments makes the study of the neutrino fog of the most relevance. This irreducible neutrino background depends on the target material as well as other experimental parameters. Recently, it has also been remarked the dependence of the neutrino fog on the DM models under consideration. In this work, we study the case of Isospin-violating dark matter (IVDM) models, discussing specific examples of DM models and making a detailed analysis of the implications of IVDM on the neutrino fog. We also explore the conditions under which this background can be mitigated for specific DM models.
