摘要:

我们讨论了中微子质量的上限,可能提供的核心坍缩超新星爆炸在我们的银河系中,如果它表现出时间变化的中微子排放量的几毫秒的规模,建议最近的二维模拟的前景。利用文献[1]中采用的小波技术对中微子发射的模拟进行分析,发现在95%的置信水平下,如果在中微子向地球传播的过程中保持发射的时间变化,则可以建立一个上限m_nu ~ 0.14 eV。

英文摘要:

We discuss the prospects for improved upper limits on neutrino masses that may be provided by a core-collapse supernova explosion in our galaxy, if it exhibits time variations in the neutrino emissions on the scale of a few milliseconds as suggested by recent two-dimensional simulations. Analyzing simulations of such neutrino emissions using the wavelet technique adopted in [1], we find that an upper limit m_nu ~ 0.14 eV could be established at the 95% confidence level if the time variations in emissions were to be preserved during neutrino propagation to the Earth.
