Status of the Measurement of Neutrino-Electron Elastic Scattering in the NOvA Near Detector

Neutrino-electron elastic scattering is a purely leptonic process whose cross section can be precisely calculated in the standard model. A measurement of this process can provide an in-situ constraint to the absolute neutrino flux in an accelerator-based νμ beam. NOvA is a long-baseline neutrino experiment optimized to observe the oscillation of muon neutrinos to electron neutrinos. It 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. This poster presents the status of the measurement of neutrino-electron elastic scattering in the NOvA near detector includes strategies for selecting events and extracting signals, as well as the prospect of reducing the uncertainty on the NuMI νμ flux.
