Abstract

The NOvA experiment is an off-axis long-baseline neutrino oscillation experiment seeking to measure $\nu_{\mu}$ disappearance and $\nu_{e}$ appearance in a $\nu_{\mu}$ beam originating at Fermilab. In addition to measuring the unoscillated neutrino spectra for the purposes of predicting the oscillated neutrino spectrum in the far detector, the 293-ton near detector also enables high-statistics investigation into neutrino scattering in numerous reaction channels. We discuss the various near detector analyses currently in progress, including inclusive measurements of both electron and muon neutrino charged-current interactions and efforts to constrain the off-axis NuMI flux using the elastic scattering of neutrinos from atomic electrons.
