未来大气实验和长基线实验之间的前景和协同作用

Prospects and synergies between future atmospheric and long-baseline experiments

Michele Maltoni

摘要:

在这次演讲中,我们将讨论未来兆吨级中微子探测器收集的大气中微子数据的物理范围。首先,我们将在一般基础上讨论大气中微子的可能性,并以地球中微子能量图的形式给出我们的结果:中微子能量-最低角平面的等值线图。在这种情况下,我们将详细分析各种签名相关的θ_13,中微子的质量等级,θ_23的八分圆和delta_CP阶段出现的中微子能量和基线的不同值。然后,我们将考虑具体的实验设置,表明大气和长基线中微子数据之间存在协同效应:两个数据集的组合比每个单独数据样本的灵敏度的简单总和要强大得多。

英文摘要:

In this talk we will discuss the physics reach of the atmospheric neutrino data collected by a future megaton-class neutrino detector. First we will discuss the potentialities of atmospheric neutrinos on general basis, presenting our results in the form of neutrino oscillograms of the Earth: contour plots in the neutrino energy--nadir angle plane. In this context we will analyze in detail the various signatures related to theta_13, to the neutrino mass hierarchy, to the octant of theta_23 and to the delta_CP phase which appear for different values of the neutrino energy and baseline. Then we will consider concrete experimental setups, showing that synergic effects exist between atmospheric and long-baseline neutrino data: the combination of the two data sets is much more powerful than the simple sum of the sensitivity of each individual data sample.
