论文摘要
我们在用于核心 - 循环超新星的辐射流体动力学的背景下为左手中微子构建手性辐射传输方程。基于手性动力学理论，该理论结合了由于费米的手性而结合了量子校正，我们通过碰撞得出了手性转移方程的一般相对论形式。我们表明，这种量子校正明确打破了系统的球形对称性和轴对称性。特别是在惯性框架中，我们发现所谓的侧跳导致中微子和物质之间的碰撞中的量子校正。我们还在中微子吸收过程的排放和吸收率中得出了这种校正的分析形式。这些校正导致物质的动力螺旋性和交叉螺旋性的产生，然后应修改物质的后续演变。该理论框架可用于研究中微子手性对核心偏离超新星进化的影响。
We construct the chiral radiation transport equation for left-handed neutrinos in the context of radiation hydrodynamics for core-collapse supernovae. Based on the chiral kinetic theory incorporating quantum corrections due to the chirality of fermions, we derive a general relativistic form of the chiral transfer equation with collisions. We show that such quantum corrections explicitly break the spherical symmetry and axisymmetry of the system. In the inertial frame, in particular, we find that the so-called side jump leads to quantum corrections in the collisions between neutrinos and matter. We also derive analytic forms of such corrections in the emission and absorption rates for the neutrino absorption process. These corrections result in the generation of kinetic helicity and cross helicity of matter, which should then modify the subsequent evolution of matter. This theoretical framework can be applied to investigate the impacts of the chirality of neutrinos on the evolution of core-collapse supernovae.
