具有时空泡沫的Robertson-Walker宇宙中的中微子振荡
Neutrino oscillations in a Robertson-Walker Universe with space time foam
摘要：
在Phys.Rev.D77（2008）105001中，我们研究了四维随机涨落时空中味振荡的退相干模型，并简要讨论了当前地球和天体物理中微子实验对此类模型的敏感性。在本附录中，我们将这些结果扩展到包含由于宇宙膨胀的影响，这样我们的分析可以用于河外高能中微子的研究，例如来自宇宙学距离的伽马射线暴的中微子。不幸的是，在弦论框架下构建的泡沫微观模型中，我们得出了悲观的结论，通过味振荡测量的退相干效应的可检测性。
英文摘要：
In Phys. Rev. D77 (2008) 105001, we have studied decoherence models for flavour oscillations in four-dimensional stochastically fluctuating space times and discussed briefly the sensitivity of current terrestrial and astrophysical neutrino experiments to such models. In this addendum we extend these results to incorporate the effects due to the expansion of the Universe, so that our analysis can be useful in studies of extragalactic high-energy neutrinos, such as those coming from Gamma Ray Bursts at cosmological distances. Unfortunately for some microscopic models of foam, constructed in the string theory framework, we arrive at pessimistic conclusions about the detectability of the decoherence effects via flavour oscillation meaurements.
