The year 2025 marks the 57th anniversary of the discovery of solar neutrinos, the 27th anniversary of the establishment of neutrino oscillation, the 22nd anniversary of the proposed Daya Bay neutrino experiment, and the second year of the Jiangmen Neutrino Experiment. At this critical juncture, the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences, the China Center for Advanced Science and Technology (CCAST) and the Hangzhou Institute for Advanced Studies of the University of Science and Technology jointly organized the Neutrino Summer School to review the history of neutrino physics and look forward to the future of neutrino physics.
The Neutrino Summer School will be held in Hangzhou, Zhejiang Province from August 17 to 24, 2025 (report on August 17 and leave on August 24). Graduate students and senior undergraduates are welcome to apply.
Neutrinos play an important role in the development of particle physics. In 1930, Pauli proposed the neutrino hypothesis to explain the continuous spectrum of electrons in Betta decay, and the neutrino later became a key link in Fermi's effective theory of the weak interaction in 1933, which can be said to be the benchmark of new physics from the beginning. Neutrinos played an important role in the hypothesis of the existence of the fourth quark after Li Zhengdao and Yang Zhenning proposed parity nonconservation in the weak interaction and the experimental discovery of muon-type neutrinos. To this day, the mixing of neutrino mass and lepton flavor remains the only new physics beyond the Standard Model of particle physics with a solid experimental basis. In addition, neutrinos are the only electrically neutral fermions in the Standard Model, and it is possible that they are Majorana particles, which can destroy the lepton number. Neutrinos are therefore an indispensable key to unlocking new physics.
随着2012年大亚湾反应堆中微子实验测量到最小的轻子味混合角，中微子振荡实验进入了精确测量的新时代。计划今年底安装完成的江门中微子实验（JUNO）将确定中微子质量顺序，同时能将中微子质量平方差和混合角的测量精度提高到百分之一以下。目前，美国的NOvA和日本的T2K实验正在对中微子CP破坏相角进行测量，初步数据显示CP破坏效应显著，这为解释宇宙中正反物质不对称提供了新的可能性。除此之外，针对自然界中存在的大气中微子、太阳中微子、超新星中微子、宇宙中微子遗迹、超高能宇宙线中微子和多信使天文学的研究也在如火如荼地进行中。中微子物理在不久的将来必然会迎来重大突破，并为建立新的粒子物理学理论奠定基础。
本次暑期学校将邀请国内从事相关前沿领域研究的资深专家进行授课，内容包括反应堆和加速器中微子实验、大气和太阳中微子实验、标准模型和新物理简介、中微子物理基础、量子场论与有效场论、中微子天文学、中微子宇宙学，同时邀请优秀的青年学者开展轻子生成机制、轻子味对称性、中微子-原子核相干散射、无中微子双贝塔衰变、中微子与暗物质等方向的前沿讲座。
- 招生对象：研究生、高年级本科生，欢迎有志于中微子理论和实验研究的年轻人申请。
- 会议组织：学员注册费1500元，统一安排住宿、费用自理；对于支付参会费用有困难的本科生，可申请减免。
