X03.00001: Ab-initio calculations of neutrino-nucleus interactions Invited Speaker: Alessandro Lovato An accurate description of neutrino interactions with nuclei is critical for the success of current and planned neutrino-oscillation experiments. I will present quantum Monte Carlo calculations, based on Green’s function Monte Carlo methods, of neutrino-12C inclusive scattering induced by neutral- and charged-current interactions. These calculations are based on realistic treatments of nuclear interactions and currents, the latter including the axial-, vector-, and vector-axial interference terms crucial for determining the difference between neutrino and anti-neutrino scattering and the CP-violating phase. The role of two-nucleon processes induced by correlation effects and electroweak currents will be discussed in detail. |

X03.00002: Electron-scattering constraints for neutrino-nucleus interactions Invited Speaker: Lawrence B Weinstein The extraction of neutrino mixing parameters from neutrino oscillation experiments relies on the reconstruction of the incident neutrino energy and on knowledge of the neutrino-nucleus interaction cross-section for various nuclei and a wide range of incident neutrino energies. There are a wide variety of electron scattering experiments at the Thomas Jefferson National Accelerator Facility which exploit the similarities between electrons and neutrinos to improve our knowledge of neutrino-nucleus scattering. These include measurements of quasi-elastic and deep inelastic scattering cross sections as well as measurements of incident lepton energy reconstruction techniques. This talk will present the results of these electron-scattering experiments and their impact on our knowledge of neutrino-nucleus interactions, including nuclear spectral and structure functions, short range correlations, and duality. It will also present the results of the first tests of lepton-energy reconstruction techniques. These tests found that only a small fraction of electron-scattering events could be reconstructed to the correct incident energy and that this fraction was badly predicted by event generators. Including the electron-scattering results should help neutrino experiments achieve their ambitious precision goals. |

X03.00003: New measurements of neutrino-nucleus interactions in Ar Invited Speaker: Anne Schukraft Neutrinos are among the least understood fundamental particles and much of their behavior remains to be explored. In order to enable experiments that are studying neutrino properties through precision measurements of neutrino oscillations, a precise understanding of what happens in an interaction of a neutrino within a nucleus is required such that predictions for the experiment can be made and observed events can be reconstructed. Several new and exciting neutrino oscillation experiments like the Deep Underground Neutrino Experiment (DUNE) use Argon as a target nucleus, which to date is not understood theoretically and experimentally. Over the last years, first measurements of neutrino-Argon interactions have been made by ArgoNeuT and are complemented and expanded by MicroBooNE. This talk will present recent measurements and review the status of the field. |
