Constraints on the Neutrino Flux in NOvA using the Near Detector Data

NOvA, a long-baseline neutrino oscillation experiment at Fermilab, is designed to measure νe appearance and νμ disappearance in the NuMI beam. NOvA is comprised of two finely segmented liquid scintillator detectors at 14 mrad off-axis in the NuMI beam, a design optimised for the study of neutrino oscillations that also enables detailed study of neutrino interactions using the NOvA Near Detector. Off-axis nature of the beam enables a narrow band beam around 2GeV. An accurate prediction of the neutrino flux is needed for precision oscillation measurements, and is critical for neutrino interaction studies. Data from the hadro-production measurements Experiments and, importantly, from the NOvA Near Detector provide powerful constraints on the νμ and νe fluxes. In particular, the measurement of the neutrino-electron elastic scattering provides an in situ constraint on the absolute flux. This talk presents the data-driven predictions of the NOvA νμ and νe flux, and outlines future improvements in the flux-calculations.
