A Search of Dark Matter Candidates in Neutrino Experiments

The existence of dark matter has been concretely established for decades by astrophysical and cosmological observations. Yet very little is known about the substance that makes up approximately 85% of the matter density of the Universe. However, with the growing scale of particle detectors and astonishing advances in the Liquid Argon TPC technology. We are on the positive outlook of discovering candidates for dark matter. Some of the promising and interesting models arise as beyond the Standard Model (SM) physics models like the leptophilic gauge bosons, axion-like particles (ALPs), heavy neutral leptons (HNLs), etc. In this work, we discuss the phenomenology of these dark sector models at neutrino facility fixed-target neutrino experiments. Neutrino experiments feature high-luminosity beams of protons that impinge upon a dense target or no target, from which neutrinos and possibly dark matter particles are produced. These dark matter particles can propagate downstream to a highly shielded detector. We analyze their decay and scattering signatures to constrain the dark matter coupling parameters with well know SM particles. We have used the data from some previous and ongoing experiments to place limits on well-motivated models of dark matter.
