Radiative Corrections for Neutrino Scattering

Richard J. Hill (U. Kentucky) is proposing a research plan where he will visit Fermilab for 4.5 months in an effort to determine the impact of electromagnetic radiative corrections on long baseline neutrino oscillation experiments. To achieve this goal, the PI proposes to (1) implement recent theoretical work by the PI and his postdoc Oleksandr Tomalak (U. Kentucky) on neutrino-electron scattering into neutrino event generators and quantify neutrino energy reconstruction capabilities at DUNE using this process; (2) compute complete electroweak radiative corrections and uncertainties to quark-level four fermion operator coefficients underlying all neutrino-nucleus scattering process; (3) extend the radiative correction formalism for application to neutrino-nucleon and neutrino-nucleus scattering. This project is of high relevance to the U.S. Neutrino program, as it has a direct impact on the major goal of the US flagship experiment DUNE, the determination of the leptonic CP violation phase.
