Description
NOvA is a long-baseline neutrino experiment optimized to observe the oscillation of muon neutrinos to electron neutrinos. It uses a high purity muon neutrino beam produced at Fermilab with central energy of approximately 1.8 GeV. NOvA consists of a near detector located 1 km downstream of the neutrino production target at Fermilab and a far detector located 810 km away in Ash River, Minnesota. Neutrino cross-section measurements performed at the near detector are affected by a large uncertainty on the absolute neutrino flux. Since the neutrino-electron elastic-scattering cross section can be accurately calculated, the measured rate of these interactions can be used to constrain the neutrino flux. We present the status of the neutrino-electron elastic-scattering measurement using a Convolutional Neural Network (CNN) to identify signal events with high purity.
