Recent Status of Neutrino Cross-Section Tuning in the NOvA Experiment

Dr. Biao Wang

The NuMI Off-axis νe Appearance (NOvA) experiment is a long-baseline neutrino oscillation experiment designed to address open questions in neutrino physics. NOvA uses two detectors, a Near Detector (ND) at Fermilab and a Far Detector (FD) in Ash River, Minnesota, 810 km away from the neutrino source. Both detectors are functionally identical, which allows for additional analysis techniques when using the ND data to mitigate systematic uncertainties such as neutrino cross-section. This presentation introduces essential analysis techniques employed by NOvA, highlighting how the Near Detector data is leveraged to improve the oscillation measurements by tuning neutrino cross-section models. And by utilizing neutrino-electron elastic scattering to provide a robust constraint on the neutrino beam flux.
