Description
NOvA is a long-baseline neutrino oscillation experiment consisting of two functionally identical tracking calorimeters, and a beam of neutrinos. The near detector is located at Fermilab, where it measures neutrinos coming from the 1 MW-capable NuMI beam. The beam can be run in neutrino or antineutrino mode, to produce a highly pure flux of muon (anti)neutrinos. The neutrinos then travel 810km north to the much larger far detector, where we measure them again after they have oscillated. By measuring the appearance of electron (anti)neutrinos and the disappearance of muon (anti)neutrinos relative to the unoscillated spectrum, we can make precise measurements of PMNS mixing matrix parameters, as well as the neutrino mass splitting $\Delta m^{2}_{32}$, and shed light on the remaining unknowns of mass ordering, $\delta_{CP}$, and the octant of $\theta_{23}$. In this talk we present the latest 3-flavor oscillation analysis results from 10 years of datataking on NOvA. This includes a nearly doubled neutrino-beam mode dataset, a new low-energy electron neutrino sample, and improvements to analysis techniques and systematics.
