This data release corresponds to the Bayesian 2024 analysis of NOvA $\nu_e$ appearance and $\nu_{\mu}$ disappearance data, corresponding to analysis described in https://doi.org/10.1103/x53y-2b86.
File `NOvA_2024_data_histograms.root` contains data histograms for all the NOvA data samples.
Exposure:
* neutrino-enhanced beam: 26.61E20 protons on target
* antineutrino-enhanced beam: 12.5E20 protons on target
External constraints:
* ss2th12=0.851, dm21=7.53e-5 are fixed at 2019 PDG values, with negligible effect on NOvA predictions.
* ss2th13 & dm32:
* RCDB1D: 1D constraint from Daya Bay for ss2th13, 0.0851+/-0.0024
* RCDB2D: Correlated 2D constraint from Daya Bay on ss2th13 & dm32, available in their official 2023 data release: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.130.161802#supplemental
An additional file containing the predictions (`NOvA_2024_prediction_with_systs_histograms.root`) for all channels’ signal and background components computed at the NOvA best-fit oscillation parameters and systematic pull terms. Numu samples include the no-oscillation case as well.
Please note that any fits performed with these histograms are not expected to exactly reproduce the official NOvA results as parameterizations of the numerous systematic uncertainties considered in the official fits are not included in this release.
The zip file also contains the 2D credible interval contours, with details in a README.md
