Status of the Electron-antineutrino Cross-section Measurement in the NOvA Near Detector

NOvA is a long-baseline neutrino oscillation experiment built to measure the rate of electron-neutrino appearance to constrain oscillation parameters: an analysis that relies on accurate estimates of the electron-antineutrino cross section. The status of a measurement of the electron-antineutrino charged-current inclusive cross section in the NOvA near detector is presented. We expect to select over 10,000 signal events in the fiducial volume of the detector over the data-taking period. The analysis employs a data-driven template-fit approach to signal estimation. Future work includes the measurement of electron neutrino to antineutrino cross-section ratios and development of an analysis framework designed for high-performance computing platforms.
