与江门中微子实验相关的中微子物理理论研究

Neutrino physics is the common hotspots of partical physics,astrophysics and cosmology at present. The Jiangmen Underground Neutrino Observatory (JUNO) is a multipurpose neutrino experiment designed to determine neutrino mass hierarchy by detecting reactor neutrinos, precisely measure three flavor neutrino oscillation mixing parameters, search for CP-violation in neutrino oscillations, observe supernova neutrinos and geo-neutrinos. Therefore, theoretical study on the neutrino physics relevant to JUNO has great significance. A large number of neutrinos will be produced during supernova explosion, and detecting supernova neutrinos will be of benefit to study neutrino fundamantal properties and mechanism of supernova explosion. This project is based on previous works, and is focused on theoretical study of the neutrino physics related to JUNO in a more comprehensive，concrete and embedded way. We will study supernova neutrino collective effect, shock wave effect, MSW effect, energy spectrum effect, terrestrial matter effect and influence of these effects on flavor evolution of supernova neutrinos, the determination of neutrino mass hierarchy and the measurement of the CP-violation phase through supernova neutrinos. We will predict supernova neutrino numbers and spectra in various physical processes that will be observed in JUNO. We will also involve in the experimental data simulation in JUNO, especially when supernova neutrinos are included.

中微子物理学目前是粒子物理、天体物理与宇宙学研究的共同热点。江门中微子实验的主要目标是通过反应堆中微子测量中微子质量顺序，精确测量三个味道中微子的混合参数和寻找中微子振荡中的CP破坏，并探测超新星中微子和地球中微子等。因此开展与江门中微子实验相关的中微子物理理论研究具有重要意义。超新星爆发产生大量的中微子，探测超新星中微子对研究中微子基本性质和超新星爆发机制很有帮助。本项目将在原有的一系列工作基础上，更加全面、具体、深入地开展与江门中微子实验相关的理论研究，包括：继续深入研究超新星中微子集体效应、震荡波效应、MSW效应、能谱效应和地球物质效应，以及这些效应对超新星中微子味演化产生的影响；给出江门中微子实验可探测到的各种物理过程的超新星中微子数目和能谱；研究利用超新星中微子确定中微子质量顺序和测量CP破坏相角的方法；参与江门中微子实验数据模拟分析，特别是结合超新星中微子的数据模拟分析。
