超新星中微子的发射角分布和味变换

Emission angle distribution and flavor transformation of supernova neutrinos

Wei Liao

摘要:

利用矩方程分析了超新星中微子的集体味变换。我们研究了矩方程的收敛性,发现使用少量矩的数值结果收敛得相当快。研究了中微子发射角分布对中微子球的影响。研究了中微子自作用哈密顿量振幅的标度律,发现它依赖于中微子发射角分布模型。研究了不同发射角分布模型对中微子振荡的影响。

英文摘要:

Using moment equations we analyze collective flavor transformation of supernova neutrinos. We study the convergence of moment equations and find that numerical results using a few moment converge quite fast. We study effects of emission angle distribution of neutrinos on neutrino sphere. We study scaling law of the amplitude of neutrino self-interaction Hamiltonian and find that it depends on model of emission angle distribution of neutrinos. Dependence of neutrino oscillation on different models of emission angle distribution is studied.
