Measurement of Muon Neutrino Disappearance with Non-Fiducial Interactions in the NO$$\nu$$A Experiment
- Minnesota U.
The NuMI (Neutrinos at the Main Injector) Off-Axis $$\nu_e$$ Appearance (NO$$\nu$$A) experiment is a long baseline neutrino oscillation experiment. The experiment measures the oscillations of a primarily muon neutrino beam using two functionally identical liquid scintillator tracking calorimeters detectors placed 810 km apart and 14 milliradians off-axis to the NuMI beam. The oscillation parameters $$\sin^2 \theta_{23}$$ and $$\left | \Delta m^2_{32} \right |$$ are measured from the disappearance of muon neutrinos as they propagate between the two detectors using the first data collected in 2014 and 2015. The primary NO$$\nu$$A analysis uses charged current events only in the fiducial volume of the far detector. This analysis also includes a non-fiducial sample of interactions that originate in the fiducial volume of the far detector but escape the detector. This analysis measures the oscillation parameters as $$\sin^2 \theta_{23}$$ = 0.31-0.71 and $$\left | \Delta m^2_{32} \right |$$ = 2. 15-2.91$$\times$$10$$^{-3}$$ eV$^2$ at 90\% confidence limits.
