WP 4 - Event selection and backgrounds

JUNO是一个大型液体闪烁中微子实验。目前正在中国南部建设中。德国团体为硬件的开发和生产做出了巨大贡献。地下实验室被挖掘出来。现在正在组装探测器。我们预计2024年将获得第一批数据。通过这个项目，我们希望参与JUNO项目的科学收获。我们希望最终确定分析策略，将其应用于数据，并为科学结果做出贡献。JUNO有一个建立在两个支柱上的多功能科学计划：中微子振荡的精确测量和使用中微子作为信使的地球和天体物理学主题。JUNO有很好的机会成为中微子物理学中最紧迫的问题之一--中微子态层次问题的决定性实验。它将比以往任何时候都更精确地测量反应堆中微子的振荡参数，测试PMNS矩阵的么正性，并寻找中微子的非标准行为。它将以前所未有的速率测量地核、地幔和地壳中的中微子，研究太阳中微子以及大气中宇宙射线产生的中微子。它在分析附近超新星的坍缩方面具有很高的潜力，它可能是第一个探测整个宇宙中超新星中微子扩散发射的实验。

JUNO is a large liquid scintillator neutrino experiment. It is under construction in Southern China. German groups contributed substantially to the development and production of the hardware. The underground laboratory was excavated. The detector is now being assembled. We expect first data in 2024. With this project we want to participate in the scientific harvest of the JUNO project. We want to finalize the analysis strategies, apply them to the data, and contribute to the scientific results. JUNO has a versatile science program built on two pillars: precision measurements of neutrino oscillations and geo- and astrophysical topics using neutrinos as messengers. JUNO has a good chance to become the decisive experiment on the question of the hierarchy of the neutrino states, one of the most pressing questions in neutrino physics. It will measure oscillation parameters from reactor neutrinos more precisely than ever before, test the unitarity of the PMNS matrix and look for non-standard behavior of neutrinos. It will measure neutrinos out of the core, the mantle, and the crust of the earth with unprecedented rates, study solar neutrinos, and neutrinos produced by cosmic rays in our atmosphere. It has a very high potential in analyzing the collapse of a nearby supernova and it will probably be the first experiment to detect the diffuse emission of neutrinos from supernovae in the whole universe.
