Abstract
New, neutrinophilic mediators are one potential extension beyond the Standard Model of particle physics. Often, studies of a neutrinophilic mediator consist of searching for direct evidence of its production and/or its tree-level virtual effect for generating strong neutrino self-interaction. In this work, we focus instead on the fact that such new mediators also lead to deviations in neutrino-matter scattering via radiative corrections. With a mediator mass well below the electroweak scale, these effects are potentially observable in a variety of contexts, including coherent elastic neutrino-nucleus scattering, neutrino deeply inelastic scattering, and neutrino-electron scattering (e.g., at Borexino). Additionally, such effects lead to new contributions to the -boson decay width and to nonstandard neutrino interactions relevant for long-baseline oscillation experiments. We explore all of these scenarios in some depth, building on the rich phenomenology associated with neutrinophilic mediators.
