Measurement of reactor neutrino oscillation with the first JUNO data

This article discusses the measurement of reactor neutrino oscillation using the first data from the JUNO experiment. It outlines the availability of source data for specific figures and mentions that raw experimental data are not publicly accessible due to their complexity and volume. The article also notes that the JUNO Collaboration develops and maintains the code used for simulations and statistical analyses, though it is not publicly distributed. Several references are provided, including Nobel lectures and a review of particle physics.

Data availability

Raw experimental data from the JUNO detectors are not publicly accessible due to their complexity and volume. Source data for Figs. 3 , 4 , and Extended Data Fig. 2 are, however, provided. Furthermore, inquiries regarding the data and posteriors used in this result may be directed to the collaboration.

Code availability

The JUNO Collaboration develops and maintains the code used for the simulation of the experimental apparatus and statistical analysis of the raw data used in this result. This code is shared among the Collaboration, but because of the size and complexity of the codebases, it is not publicly distributed. Inquiries regarding the algorithms and methods used in this result may be directed to the Collaboration.
