Description
Precise understanding of neutrino-nucleus cross sections is necessary for neutrino oscillation experiments to make accurate measurements of neutrino oscillation parameters, such as the CP violation phase $\delta_{CP}$, the mixing angle $\theta_{23}$, and the neutrino mass hierarchy. The NOvA Near Detector provides an excellent environment to make measurements of neutrino cross sections due to the high neutrino flux. The NOvA experiment uses the (anti)neutrino beam produced at Fermilab in the primary neutrino energy range of 1-5 GeV. In this poster, we present the status of a triple differential muon antineutrino cross-section measurement with respect to the antimuon kinetic energy, cosine of the antimuon scattering angle with respect to the beam, and the available energy of the event in the detector. The available energy is a model-independent measure of the hadronic energy. Simulation estimates the sample used in the analysis to be approximately 90% pure with 32% selection efficiency and containing roughly 1 million events, resulting in a systematically constrained, rather than statistically limited, measurement.
