论文摘要
核心折叠超新星模拟的稳定进步需要对热和密集物质中的中微子过程进行更精确的描述。在这项工作中，我们研究了超新星物质中（抗）muons的带电电流（CC）弱过程的速率。在相对论的平均野外水平上，我们得出了CC中微子核子反应速率的结果，考虑到完整的运动学，弱磁性和伪尺度术语以及$ Q^2 $依赖性的核子形式在HADRONIC电流中。除了muonic的半衰减过程外，我们还考虑了纯粹的松性过程。特别是，我们表明，在密度$ \ gtrsim 10^{13}〜\ rm {g〜cm^cm^{ - 3}} $的情况下，倒数衰减可以统治低能$ν_μ$和$ \barν_e$的不透明。
The steady advance in core-collapse supernova simulations requires a more precise description of neutrino processes in hot and dense matter. In this work, we study the rates of charged-current (CC) weak processes with (anti)muons in supernova matter. At the relativistic mean field level, we derive results for the rates of CC neutrino-nucleon reactions, taking into account full kinematics, weak magnetism and pseudoscalar terms, and $q^2$-dependent nucleon form factors in the hadronic current. In addition to muonic semileptonic processes we also consider purely leptonic processes. In particular, we show that inverse muon decay can dominate the opacities for low energy $ν_μ$ and $\barν_e$ at densities $\gtrsim 10^{13}~\rm{g~ cm^{-3}}$.
