Description

Neutrinos elastically scattering off atomic electrons 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 $\nu_\mu$ beam. NOvA is
a long-baseline neutrino experiment optimized to observe the oscillation
of $\nu_\mu$ to $\nu_e$. 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 talk presents the status of the
neutrino-electron elastic scattering measurement using the NOvA near
detector, including strategies for selecting the signal, as well as the prospect
of reducing the flux uncertainty.
