关于早期宇宙中微子的某些性质

On Some Properties of the Neutrino in The Early Universe

S Mani, A Sagari, B Chakrabarti, A Bhattacharya

摘要:

早期宇宙中中微子的性质已经被研究,并在早期宇宙的质量密度的一个小的不均匀性。在研究中微子的平均自由程和质量束缚时发现了对这个因子的依赖性。用一个自由波包来描述中微子的时间过程,研究了中微子味的振荡,得到了一些有趣的结果。

英文摘要:

The properties of the neutrino in the early universe have been investigated incorporating a small inhomogeneity in the mass density of the early universe. Dependence on this factor is found in studying mean free path and mass bound of neutrinos. The oscillations of neutrinos flavours have been studied by assuming a free wave packet to represent the time progression of the neutrino yielding interesting results.
