Abstract
NOvA is a long baseline neutrino oscillation experiment at Fermi National Accelerator Laboratory, USA. It is one of the so-called “off-beam-axis” experiments with two highly active detectors separated by 810 km of Earth’s crust. Both detectors are identical and consist of PVC cells filled with a liquid scintillator. The NOvA collaboration has already published its first results for muon neutrino disappearance [1] and electron neutrino appearance [2] mode with data collected between July 2013 and March 2015. This talk is devoted to a discussion on NOvA’s first results.
Highlights
NOvA (NuMI Off-Axis νe-Appearance) is a long baseline neutrino oscillation experiment consisting of two functionally identical detectors, which have been placed 14 mrad off-axis
The NOvA detectors were under construction during the first analysis data taking period, from July 2013 to March 2015
During this period 3.45 ×1020 POT were delivered to the carbon target
Summary
NOvA (NuMI Off-Axis νe-Appearance) is a long baseline neutrino oscillation experiment consisting of two functionally identical detectors, which have been placed 14 mrad off-axis. The NuMI (Neutrinos at the Main Injector) facility at the Fermi National Accelerator Laboratory (USA) provides a muon (anti-)neutrino beam for the experiment. The NOvA detectors can measure the transition probabilities P(νμ → νe) and P(νμ → νμ) From these measurements NOvA is able to extract oscillation parameters: Δm232, mixing angle θ23, CP violating phase δCP and neutrino mass hierarchy. NOvA published its first results [1], [2] this year. These results are based on data collected between July 2013 and March 2015. More data and results will be presented at the Neutrino 2016 summer conference
