Abstract: Current ton-scale, xenon-based dark matter (DM) direct detection experimentshave now reached the sensitivity required to observe solar neutrinos, marking the onset of theso-called neutrino fog. In this work, we explore how this fog is modified when either neutrinosor DM interact with nuclei through a new scalar, vector or axial-vector interaction, consideringboth heavy and light mediators. Using the latest nuclear-recoil data from XENONnT, whichshow indications of coherent elastic neutrino – nucleus scattering from8B solar neutrinos,we derive new strong bounds on couplings of light mediators. We find that these limits aresignificantly more stringent when the mediator couples to DM, rather than when new physicsaffects only neutrino interactions. Building on these results, we recompute the expectedneutrino fog and compare it with the corresponding constraints on spin-independent andspin-dependent DM-nucleon interactions. We show that the morphology of the neutrinofog can be markedly modified if either neutrinos or DM interact with nuclei through lightmediators, even in light of these recent constraints
