Kasner时空中的中微子振荡相位

Interference phase of mass neutrino in Kasner Space-time

研究了质量中微子在Kasner时空特殊情况下的传播相位和振荡特征长度,得到了中微子的零短程线相位是短程线相位一半的关系.当参数a=0时,Kasner时空中的传播相位和史瓦希时空中的相同.这一问题的研究在宇宙学中是有意义的[1—3].

In Kasner space-time,we calculate the interference phase and oscillation length of the mass neutrinos in some special cases and find that the phase along the null is equivalent to the half phase along the geodesic in the high energy limit. When the parameter a in line element fulfils a = 0,the interference phase is the same as that in Schwarzschild space-time. Research on this subject has impact on cosmology.
