Poster Neutrino oscillation

### Description

NOvA is a two detector, long-baseline neutrino oscillation experiment situated at Fermilab, Batavia, IL, USA. It is primarily designed to constraint the neutrino oscillation parameters using muon neutrino (anti-neutrino) disappearance data and electron neutrino (anti-neutrino) appearance data. NOvA detects neutrinos from Fermilab’s Neutrinos at Main Injector (NuMI) beamline. The unoscillated muon neutrino and beam $\nu_e$ events are observed by the Near Detector (ND), which is 100m deep underground and at a distance of 1km from the beam source. The Far Detector (FD), situated 809 km away from the ND, is in Ash River, MN, USA, and observes the $\nu_\mu$ and $\nu_e$ events after oscillations.

Traditionally, NOvA has used $\nu_e$ ($\bar{\nu}_e$) events in the energy range $1 < E_\nu < 4$ GeV for 3-flavor neutrino oscillation analyses to constraint the neutrino oscillation parameters. This poster discusses the impact of including high-energy neutrino events with energies up to 12 GeV in the analysis with the aim of constraining the beam electron
neutrino/antineutrino background events. Event count predictions and Asimov sensitivities after adding these high-energy sample events are presented.
