Description

NOvA, is a two-detector, long-baseline neutrino oscillation experiment located at Fermilab, Batavia, IL, USA. The NOvA experiment was designed primarily to constrain neutrino oscillation parameters by analyzing ${\nu }_{\mu }({\overline{\nu }}_{\mu })$ disappearance and ${\nu }_e({\overline{\nu }}_e)$ appearance data observed at the far detector. The Neutrinos at Main Injector (NuMI) beamline at Fermilab provides a high purity beam of neutrinos and anti-neutrinos to the experiment. The NOvA experiment consists of two functionally identical, finely granulated liquid tracking calorimeters, both situated 14.6 mrad off-axis to the beam direction. The NOvA near detector, situated 100 meters underground and 1 kilometer from the beam source, detects the non-oscillated ${\nu }_{\mu }({\overline{\nu }}_{\mu })$ and beam ${\nu }_e({\overline{\nu }}_e)$ events. The far detector, located in Ash River, MN, USA, 810 kilometers from the beam source, records the non-oscillated ${\nu }_{\mu }({\overline{\nu }}_{\mu })$ and the oscillated ${\nu }_{\mu }({\overline{\nu }}_{\mu })\to {\nu }_e({\overline{\nu }}_e)$ events. The most recent measurements of three flavor neutrino oscillation parameters based on an analysis of the data collected from neutrino-beam exposure of $26.60\times {10}^{20}$ POT and anti-neutrino beam exposure of $12.50\times {10}^{20}$ POT including an additional low energy ${\nu }_e$ sample, will be presented in this talk.
