Description
NO$\nu$A is a long-baseline accelerator neutrino experiment at Fermilab that aims at precision neutrino oscillation analyses and cross-section measurements. Large uncertainties on the absolute neutrino flux affect both of these measurements. Measuring neutrino-electron elastic scattering provides an in-situ constraint on the absolute neutrino flux. In this analysis the signal is a single, very forward-going electron shower with
$E_{e}{\theta_{e}}^{2}$ peaking around zero. After the electron selection, the primary background for this analysis is the beam $\nu_{e}$ charged current events ($\nu_{e}$ CC). Muon removed electron-added (MRE), events are constructed from $\nu_{\mu}$ CC interactions by removing the primary muon track and simulating an electron in its place. It helps us to understand the consequence of
hadronic shower mismodelling on $\nu_{e}$ selection. This talk presents an overview of on-going MRE studies and a plan for how this sample can be used to provide a data-driven constraint on the $\nu_{e}$ CC backgrounds present in the $\nu$-e analysis.
