Title: Electron neutrino appearance in the NOvA experiment

Abstract

NOvA is an off-axis, two-detector experiment studying neutrino oscillations with the ν(µ) beam from Fermilab. This paper describes the ν _e appearance analysis, including data-driven constraints from Near Detector measurements. The data set corresponds to an exposure equivalent to 6.05 × 10 ²⁰ protons-on-target in the Far Detector. Here, we observed 33 ν _e candidates with a predicted background of 8.2 ± 0.8 (syst.), for a significance of appearance higher than 8σ. Preliminary results for the allowed values of δ _CP and θ ₂₃ in both hierarchies are presented.

Constraints on oscillation parameters from $v_{e}$ appearance and $v_{μ}$ disappearance in NOvA

Journal Article Adamson, P. ; Aliaga, L. ; Ambrose, D. ; ... - Physical Review Letters

Results are reported from an improved measurement of ν _μ → ν _e transitions by the NOvA experiment. Using an exposure equivalent to 6.05 × 10 ²⁰ protons on target, 33 νe candidates are observed with a background of 8.2 ± 0.8 (syst.). In this paper, combined with the latest NOvA νμ disappearance data and external constraints from reactor experiments on sin ²2θ ₁₃, the hypothesis of inverted mass hierarchy with θ ₂₃ in the lower octant is disfavored at greater than 93% C.L. for all values of δ _CP.

First neutrino oscillation measurements in NOvA

Journal Article Messier, M. D. - Nuclear Physics. B

In this study, the NOvA experiment uses the Fermilab NuMI neutrino beam and a newly constructed 14 kt detector to address several open questions in neutrino oscillations including the neutrino mass hierarchy, the precise value of the angle θ ₂₃, and the CP-violating phase δ _CP. The experiment has been running since 2014 and has recently released its first results from an equivalent exposure of 2.74 × 10 ²⁰ protons-on-target equal to 8% of the eventual data set. Measurements of ν _μ → ν _μ oscillations find Δm ² ₃₂ = (2.52 ^+0.2 _–0.18) × 10 ^-3 eV ² andmore »« less

Improved search for muon-neutrino to electron-neutrino oscillations in MINOS

Journal Article Adamson, P. - Physical Review Letters

The authors report the results of a search for ν ^e appearance in ν ^μ beam in the MINOS long-baseline neutrino experiment. With an improved analysis and an increased exposure of 8.2 x 10 ²⁰ protons on the NuMI target at Fermilab, they find that 2 sin ² (θ ₂₃ sin ² (θ ₁₃) < 0.12 (0.20) at 90% confidence level for δ = 0 and the normal (inverted) neutrino mass hierarchy, with a best fit of 2 sin ²θ ₂₃) sin ² (2θ ₁₃) = 0.041 _-0.031 ^+0.047 (0.079 _-0.053 ^+0.071). The θ ₁₃= 0 hypothesis is disfavored bymore »« less

Physics potential of a long-baseline neutrino oscillation experiment using a J-PARC neutrino beam and Hyper-Kamiokande

Journal Article Abe, K. ; Aihara, H. ; Andreopoulos, C. ; ... - Progress of Theoretical and Experimental Physics

Hyper-Kamiokande will be a next generation underground water Cherenkov detector with a total (fiducial) mass of 0.99 (0.56) million metric tons, approximately 20 (25) times larger than that of Super-Kamiokande. One of the main goals of Hyper-Kamiokande is the study of CP asymmetry in the lepton sector using accelerator neutrino and anti-neutrino beams. In this work, the physics potential of a long baseline neutrino experiment using the Hyper-Kamiokande detector and a neutrino beam from the J-PARC proton synchrotron is presented. The analysis uses the framework and systematic uncertainties derived from the ongoing T2K experiment. With a total exposure of 7.5more »« less

Search for active-sterile neutrino mixing using neutral-current interactions in NOvA

Journal Article Adamson, P. ; Aliaga, L. ; Ambrose, D. ; ... - Physical Review D

Here, we report results from the first search for sterile neutrinos mixing with active neutrinos through a reduction in the rate of neutral-current interactions over a baseline of 810 km between the NOvA detectors. Analyzing a 14-kton detector equivalent exposure of 6.05 × 10 ²⁰ protons-on-target in the NuMI beam at Fermilab, we observe 95 neutral-current candidates at the Far Detector compared with 83.5 ± 9.7(stat) ± 9.4(syst) events predicted assuming mixing only occurs between active neutrino species. No evidence for νμ→νs transitions is found. Interpreting these results within a 3+1 model, we place constraints on the mixing angles θ ₂₄more »« less
