大气中微子振荡和冰中的τ中微子

Atmospheric neutrino oscillations and tau neutrinos in ice

Gerardo Giordano, Olga Mena, Irina Mocioiu

摘要:

冰立方深核阵列的主要目标是寻找天体物理起源的中微子。大气中微子通常被认为是这些搜索的背景。我们在这里表明,冰立方深核阵列的级联测量可以提供强有力的证据,大气中微子振荡中的τ中微子外观。仔细研究这些τ中微子是至关重要的,因为它们构成了天体物理中微子探测的不可约背景。

英文摘要:

The main goal of the IceCube Deep Core Array is to search for neutrinos of astrophysical origins. Atmospheric neutrinos are commonly considered as a background for these searches. We show here that cascade measurements in the Ice Cube Deep Core Array can provide strong evidence for tau neutrino appearance in atmospheric neutrino oscillations. A careful study of these tau neutrinos is crucial, since they constitute an irreducible background for astrophysical neutrino detection.
