核心坍缩超新星的中微子爆发不仅可以提供关于爆炸机制和原中子星星冷却机制的信息，而且还可以提供关于中微子的内在性质如味振荡的信息。一个重要的问题是了解在观测单个超新星时，超新星和中微子物理学能在多大程度上解耦。本文概述了用液氩探测器探测超新星中微子的可能性，并讨论了中微子混合角θ13和质量等级类型。此外，还定量研究了约束超新星参数的可能性。需要一个非常大的液氩探测器（100千吨）来进行这些参数的精确测量。此外，这些探测器还可以提供关于弥漫超新星中微子背景的νe分量的信息。
The neutrino burst from a core collapse supernova can provide information about the explosion mechanism and the mechanisms of proto neutron star cooling but also about the intrinsic properties of the neutrino such as flavor oscillations. One important question is to understand to which extent can the supernova and the neutrino physics be decoupled in the observation of a single supernova. The possibility to probe the neutrino mixing angle θ13 and the type of mass hierarchy from the detection of supernova neutrinos with liquid argon detectors is summarized in this paper. Moreover, a quantitative study about the possibility to constrain the supernova parameters is presented. A very massive liquid argon detector (≈ 100 kton) is needed to perform accurate measurements of these parameters. In addition, these detectors could also provide information on the νe component of the diffuse supernova neutrino background.
