Data release for the “Measurement of the charged-current electron (anti-)neutrino inclusive cross-sections at the T2K off-axis near detector ND280”
This data release is associated with the publication “Measurement of the charged-current electron (anti-)neutrino inclusive cross-sections at the T2K off-axis near detector ND280”. It is currently available on arXiv and in JHEP:
arXiv:2002.11986 [hep-ex] and J. High Energ. Phys. 2020, 114 (2020)
When citing this data release, please cite as well the paper.
The full author list and acknowledgements for the T2K collaboration are described in the article.
The data release contains:
- cross-section measurements with NEUT 5.3.2 (fraction and total with covariances)
- cross-section measurements with GENIE 2.8.0 (fraction and total with covariances)
- smearing matrices for selected electron/positron momentum
Description:
The cross-section measurements are provided in the form of text files and a PDF summary. The detailed method and results are presented in the paper (especially section 8).
The smearing matrices are provided as one ROOT file with two 2D histograms showing the electron/positron smearing matrices for momentum and angle, obtained using the selection from the ND280 nue CC inclusive analysis. It is similar to the figure 10 of the paper, but with more statistics and finer binning. They are accompanied with a README file presenting how to use these matrices and the related caveats. Please read it carefully.
We strongly encourage any users of the matrices to present these caveats alongside any public comparison to T2K data.
Full abstract:
The electron (anti-)neutrino component of the T2K neutrino beam constitutes the largest background in the measurement of electron (anti-)neutrino appearance at the far detector. The electron neutrino scattering is measured directly with the T2K off-axis near detector, ND280. The selection of the electron (anti-)neutrino events in the plastic scintillator target from both neutrino and anti-neutrino mode beams is discussed in this paper. The flux integrated single differential charged-current inclusive electron (anti-)neutrino cross-sections, dσ/dp and dσ/dcos(θ), and the total cross-sections in a limited phase-space in momentum and scattering angle (p>300 MeV/c and θ≤45∘) are measured using a binned maximum likelihood fit and compared to the neutrino Monte Carlo generator predictions, resulting in good agreement.
