Description
Nuclear reactors provide intense neutron-capture environments and can act as controlled terrestrial sources of MeV-scale dark-sector particles. In this talk, I will discuss reactor-produced dark photons and dark matter from nuclear de-excitation. In the kinetically mixed vector-portal framework, excited nuclei can emit an on-shell vector mediator via N* -> N V, which can either decay visibly or invisibly into a dark matter pair. The visible-decay channel probes MeV-scale dark photons, while the invisible-decay channel produces a flux of sub-MeV dark matter.
