第五届JUNO相关的理论和唯象研讨会
------首个物理成果专题研讨会------
English version follows
2025年8月26日，江门中微子实验（JUNO）正式运行。2025年11月19日，JUNO发布了其首个物理成果。经过不到两个月时间的取数，JUNO就把对ν₁ 和 ν₂两个中微子的质量平方差和对应的混合角的测量精度提高到了1.6%和2.8%。这一精度超出过去三十年国际上所有中微子实验探测的总和。
JUNO首次运行即取得重要成果，这为实验的后续研究提供了坚实的信心保障。接下来，JUNO将围绕其首要目标——确定中微子的质量顺序（正序 m₁<m₂<m₃ 或者倒序 m₃<m₁<m₂ ）——进行探测。除了首要目标外，在未来运行的若干年里，它还会在轻子味混合参数的精确测量、质子衰变、超新星中微子、太阳中微子、大气中微子、超出标准模型的新物理等诸多方面进行实验测量，有可能在多个方面获得重要成果，甚至是一些不可预期的发现。
以JUNO为代表的全球中微子精确测量时代已经到来。JUNO，以及后面几年将会运行的日本顶级神冈实验（Ηyper-Kamiokande）和美国的深地中微子实验（DUNE），将会代表这个时代最重要的几个中微子实验，为实验上彻底解决中微子振荡问题给出最终答案。
本次研讨会将以JUNO公布首个物理成果为契机，探讨江门实验可能带来的物理应用，实验结果对未来中微子理论走向的影响，以及实验探测背后的一些故事。欢迎感兴趣的同行专家参加！

The 5th Workshop on JUNO-related Theory and Phenomenology
--- Specified Workshop on First Physical Achievement in JUNO ---
On August 26, 2025, the JUNO experiment officially started data collection. On November 19, 2025, JUNO released its first result. After collecting data for less than two months, JUNO has already improved the precision of the mass-squared difference between the ν₁ and ν₂ neutrinos as well as the corresponding mixing angle to 1.6% and 2.8%, respectively. Its precision level surpasses the combined achievements of all neutrino experiments around the world over the past three decades.
JUNO’s first run has yielded significant results, providing strong confidence for the future research of neutrino experiments. Next, JUNO will focus on its primary goal: determining the neutrino mass ordering (normal ordering m₁<m₂<m₃ or inverted ordering m₃<m₁<m₂). Beyond this, JUNO will also conduct experimental measurements in many different fields in the coming years of operation, including precision measurements of the lepton flavor mixing parameters, proton decay, supernova neutrinos, solar neutrinos, atmospheric neutrinos, and searches for new physics beyond the Standard Model. JUNO may achieve major breakthroughs in multiple areas, and even make unexpected discoveries.
The era of high-precision neutrino measurements, represented by JUNO, has now begun. JUNO—together with the Hyper-Kamiokande experiment in Japan and the DUNE experiment in US, both scheduled to begin operation in the coming years—will serve as the most important neutrino experiments in the coming years. They will provide the final answers for fully resolving our quest of neutrino oscillations.
Taking JUNO’s first physics results as an opportunity, this workshop will discuss the potential physics applications of the Jiangmen experiment, its implications for the future development of neutrino theory, and the stories behind the experiment’s achievements. We warmly welcome interested colleagues and experts to participate!
