Exploring neutrino & antineutrino oscillations with NOvA

Abstract: The NOvA experiment is an off-axis long-baseline neutrino oscillation experiment using the NuMI $\nu_{\mu}$ beam originating at Fermilab. By examining the disappearance of muon neutrinos and the appearance of electron neutrinos between the near detector at Fermilab and the far detector in Ash River, MN, NOvA has the potential to help answer a number of fundamental questions: Are the neutrinos' masses ordered the same way as those of the charged leptons? Are there underlying symmetries in the way the neutrino states mix with one another? Do leptons experience charge-parity violation? In this talk I will present NOvA's most recent results utilizing muon neutrino disappearance and electron neutrino appearance with both neutrinos and antineutrinos. In addition to the world's first significant ($>4\sigma$) observation of electron antineutrino appearance in a muon antineutrino beam, I will discuss constraints on the oscillation parameters of interest and their implications regarding the questions outlined above.
