中微子源和中微子望远镜中UHE中微子的味成分

Flavor Composition of UHE Neutrinos at Source and at Neutrino Telescopes

Sandhya Choubey, Werner Rodejohann

摘要:

我们将高能天体物理中微子的初始通量组成参数化为(Phi_e^0:Phi_mu^0:Phi_tau^0)=(1:n:0),其中n是源的特征。所有通常假设的中微子源都是这个简单参数化的极限。我们将研究中微子望远镜如何精确地确定n的值。我们还表明,有一个中微子混合的情况下,μ子中微子的比例,其他中微子采取一个恒定的值,无论初始通量的组成。这发生在μ子中微子的生存概率取其最小允许值时。这个非常预测中微子混合的情况下的唯象后果。

英文摘要:

We parameterize the initial flux composition of high energy astrophysical neutrinos as (Phi_e^0 : Phi_mu^0 : Phi_tau^0) = (1 : n : 0), where n characterizes the source. All usually assumed neutrino sources appear as limits of this simple parametrization. We investigate how precise neutrino telescopes can pin down the value of n. We furthermore show that there is a neutrino mixing scenario in which the ratio of muon neutrinos to the other neutrinos takes a constant value regardless of the initial flux composition. This occurs when the muon neutrino survival probability takes its minimal allowed value. The phenomenological consequences of this very predictive neutrino mixing scenario are given.
