Abstract

Light particles from dark sectors are often targets of theoretical and experimental scrutiny by the Particle and Astroparticle Physics communities, where several experiments have been proposed in the past years devoted to probing the existence of those particles. Considering the international relevance and ongoing community effort, this post-doctorate proposal plans to assess the signature of light particles in low-energy accelerators and neutrino detectors. This approach is necessary due to the fact that the mass range of those particles makes neutrino detectors and low-energy accelerators such as DUNE and SHiP excellent laboratories, with clear advantages compared to high-energy accelerators such as the LHC. Besides all these detector and particle physics aspects involved in the project, we will solve the Boltzmann equation to outline the region of parameter space where the correct dark matter relic density is found according to Planck data. Therefore, we believe that our work will significantly contribute to the search for dark sectors and pave the road toward new physics. (AU)
