论文摘要
由于实验性中微子物理学和观察性天文学的成就,在过去的二十年中,在过去的二十年中,对天体物理来源中的中微子风味振荡的研究得到了增强。在这里,我们讨论了两个兴趣的案例,即在短和长伽马射线爆发(GRB)的建模中:高临界,即高度超级 - 埃德丁顿球形/磁盘积聚到中子星(NS)/黑洞(BH)上。我们表明,在这两个系统中,密度和温度的环境条件都意味着中微子风味振荡的发生,并具有中微子自我相互作用的相关作用。
The study of neutrino flavour oscillations in astrophysical sources has been boosted in the last two decades thanks to achievements in experimental neutrino physics and observational astronomy. We here discuss two cases of interest in the modelling of short and long gamma-ray bursts (GRBs): hypercritical, i.e. highly super-Eddington spherical/disk accretion onto a neutron star (NS)/black hole (BH). We show that in both systems the ambient conditions of density and temperature imply the occurrence of neutrino flavour oscillations, with a relevant role of neutrino self-interactions.
