Abstract

The NOvA experiment is a long-baseline neutrino experiment designed to study the oscillation behavior of neutrinos and antineutrinos, utilizing Fermilab’s Megawatt-capable NuMI neutrino beam. Over the past 10 years, NOvA has collected data from two functionally identical tracking calorimeter detectors, which are situated off the NuMI beam axis and separated by 810 km. The construction of the experiment enables observation of muon (anti)neutrino disappearance and electron (anti)neutrino appearance. Consequently, precision measurements of oscillation parameters, including the mass splitting \(\Delta m_{32}^{2}\) and its sign, the mixing angle \(\theta_{23}\) , and the phase of \(CP\) -symmetry violation, can be obtained. This paper presents an overview of the NOvA experiment and its latest results.
