中微子工厂的近距离探测器物理学

Physics with near detectors at a neutrino factory

Jian Tang, Walter Winter

摘要:

我们讨论了中微子工厂附近探测器对标准振荡和非标准相互作用测量的影响。我们的系统学处理包括截面误差,通量误差,和背景的不确定性,和我们的近探测器通量包括中微子源和探测器的几何形状。而不是一个特定的探测器的概念,我们引入了定性的不同类别的近探测器具有不同的特性,如近探测器捕捉整个中微子通量(近探测器的限制)与近探测器观察光谱类似的远探测器(远探测器的限制)。我们在讨论中包括低能中微子工厂。我们说明了需要在探测器附近进行测量,讨论了需要多少,以及通量监测的作用是什么。例如,我们证明,近探测器是强制性的领先的大气参数测量,如果中微子工厂只有一个基线,而系统的错误部分取消,如果中微子工厂复杂的魔术基线。最后,近检测器与nu_tau检测被证明是有用的非标准的相互作用。

英文摘要:

We discuss the impact of near detectors at a neutrino factory both on standard oscillation and non-standard interaction measurements. Our systematics treatment includes cross section errors, flux errors, and background uncertainties, and our near detector fluxes include the geometry of the neutrino source and the detector. Instead of a specific detector concept, we introduce qualitatively different classes of near detectors with different characteristics, such as near detectors catching the whole neutrino flux (near detector limit) versus near detectors observing a spectrum similar to that of the far detector (far detector limit). We include the low energy neutrino factory in the discussion. We illustrate for which measurements near detectors are required, discuss how many are needed, and what the role of the flux monitoring is. For instance, we demonstrate that near detectors are mandatory for the leading atmospheric parameter measurements if the neutrino factory has only one baseline, whereas systematical errors partially cancel if the neutrino factory complex includes the magic baseline. Finally, near detectors with nu_tau detection are shown to be useful for non-standard interactions.
