Searches for new physics are conducted in different experimental conditions, e.g. at high energy colliders or with high intensity particle beams. The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for the study of a variety of physics topics, due to its high-intensity proton beams that provide large neutrino fluxes, and which are sampled by a near detector system consisting of a combination of capable precision detectors, and by the very massive far detector system located deep underground.
Recently, such accelerator-based neutrino experiments have been recognised as excellent tools to search for new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM), including so-called feebly interacting particles (FIPs).
We will show some examples of present searches at neutrino experiments and will then discuss DUNE’s sensitivities specifically to sterile neutrino mixing, heavy neutral leptons, non-standard interactions, CPT symmetry violation, Lorentz invariance violation, neutrino trident production, dark matter from both beam induced and cosmogenic sources, baryon number violation, and other new physics topics that complement those at high-energy colliders and extend the present reach.
