包括活性-无菌中微子混合的液体微中子相互作用

Neutrino interactions in liquid scintillators including active-sterile neutrino mixing

M. M. Saez, M. E. Mosquera, O. Civitarese

摘要:

中微子在核心坍缩超新星事件中起着重要作用,因为它们是理解爆炸机制的关键。对中微子通量的分析可以回答中微子的相关问题,例如:本文研究了中微子振荡和eV无菌中微子的存在对超新星中微子流$F_ν(E)$的影响。我们计算了超新星中微子流的能量分布和在液体闪烁体中探测到的事件总数。我们还提出了一个分析的转换概率作为一个功能的活性-无菌中微子混合参数。最后,我们进行了统计分析,以提取该模型的混合参数的值。

英文摘要:

Neutrinos play an important role in core-collapse supernova events since they are a key piece to understand the explosion mechanisms. The analysis of the neutrino fluxes can bring answers to neutrino's related problems e.g.: mass hierarchy, spectral splitting, sterile neutrinos, etc. In this work we study the impact of neutrino oscillations and the possible existence of eV sterile neutrinos upon the supernova neutrino flux $F_ν(E)$. We have calculated the energy distribution of the neutrino flux from a supernova and the total number of events which would be detected in a liquid scintillator. We also present an analysis for the conversion probabilities as a function of the active-sterile neutrino mixing parameters. Finally, we have carried out a statistical analysis to extract values for the mixing parameters of the model.
