Low Energy Neutrino Science and Applications

Low energy neutrinos have been an essential probe at the frontier of physics for the last century exploring both the properties of the neutrino and the weak interactions with nuclear matter. Neutrinos are the second most ubiquitous particle in the universe, after the photon, and their very existence with a non-zero mass breaks our most tested theory of particles and forces. Finding a solution has stumped theorists and experimentalists for more than two decades and represents one of the greatest challenges to the entire field. Precision measurements that are sensitive to other ways that neutrinos deviate from expectation are key to moving forward. The neutrino mass and Dirac or Majorana nature are pursued by nuclear beta and double beta decay experiments. The global reactor neutrino experiments have provided some of the most stringent tests of the extremely successful 3-flavor paradigm and the US-hosted PROSPECT experiment has demonstrated the feasibility of precision short baseline operations at the surface. The recent observations of coherent elastic neutrino nuclear scattering by COHERENT on multiple nuclei provide a new probe of nuclear physics and physics beyond the standard model. These developments also bring new opportunities for neutrino applications including nuclear non-proliferation and nuclear power operations. In this talk, we will consider the current landscape of low energy neutrino experiments and the impact of new technological developments enabling the next generation of science and applications.
