通过Turbulence的受激中微子转换

Stimulated Neutrino Transformation Through Turbulence

Kelly M. Patton, James P. Kneller, Gail C. McLaughlin

摘要:

我们推导出一个解析解的味道演变的中微子通过湍流密度分布,发现准确地预测的振幅和过渡波长的数值解的情况下,逐案的基础上。演化被认为强烈依赖于湍流中的傅立叶模式,这些模式与中微子本征值之间的分裂大致相同。湍流中的傅里叶模与中微子本征值之间的分裂近似相同,强烈地增强了跃迁。我们还发现,由于长波长模式的振幅和波数的比率的顺序,或大于贝塞尔函数$J_0$的第一根时,过渡的抑制。

英文摘要:

We derive an analytical solution for the flavor evolution of a neutrino through a turbulent density profile which is found to accurately predict the amplitude and transition wavelength of numerical solutions on a case-by-case basis. The evolution is seen to strongly depend upon those Fourier modes in the turbulence which are approximately the same as the splitting between neutrino eigenvalues. Transitions are strongly enhanced by those Fourier modes in the turbulence which are approximately the same as the splitting between neutrino eigenvalues. We also find a suppression of transitions due to the long wavelength modes when the ratio of their amplitude and the wavenumber is of order, or greater than, the first root of the Bessel function $J_0$.
