轻子混合的红外起源及其在DeepCore的检验

An infrared origin of leptonic mixing and its test at DeepCore

F. Terranova

摘要:

费米子混合通常被认为是一个基本理论的低能表现,其能量尺度比电弱尺度大得多。本文研究了描述轻子混合的参数实际上来自中微子相互作用场的低能行为的可能性。特别是,我们推测,对于一个给定的过程的混合角的测量值取决于不可观测的风味状态的过程中的能量的数量。我们提供了一个协变实现这样的猜想,得出其后果在两个中微子家庭近似和比较这些发现与当前的实验数据。最后,我们表明,这种混合的红外起源将体现在冰立方深核阵列,它测量大气振荡的能量远远大于τ轻子质量;因此,它将在很短的时间尺度上进行实验测试。

英文摘要:

Fermion mixing is generally believed to be a low-energy manifestation of an underlying theory whose energy scale is much larger than the electroweak scale. In this paper we investigate the possibility that the parameters describing lepton mixing actually arise from the low-energy behavior of the neutrino interacting fields. In particular, we conjecture that the measured value of the mixing angles for a given process depends on the number of unobservable flavor states at the energy of the process. We provide a covariant implementation of such conjecture, draw its consequences in a two neutrino family approximation and compare these findings with current experimental data. Finally we show that this infrared origin of mixing will be manifest at the Ice Cube DeepCore array, which measures atmospheric oscillations at energies much larger than the tau lepton mass; it will hence be experimentally tested in a short time scale.
