Do neutrinos violate the one of the most fundamental symmetry in particle physics? Could they explain the matter-antimatter asymmetry in the Universe? How much information can neutrinos provide about supernovae explosions? Within the next decade, the Deep Underground Neutrino Experiment (DUNE) will address these burning questions in neutrino physics by making full use of the cutting-edge technology of the Liquid Argon Time Projection Chamber (LArTPC). However, given the high level of precision needed to reach its goals, the DUNE LArTPC will need to be well-understood over a wide range of particle types and energies.<br /><br />During this seminar, I will introduce the DUNE experiment and its physics goals before focusing on the use of neutrons as a calibration method in liquid argon detectors. I will then present the ACED experiment, carried out by the UC Davis neutrino group at the Los Alamos National Laboratory, and our measurement of the neutron capture cross section in argon.</p><p> </p>
