探测DUNE附近探测器的源和探测器NSI参数

Probing Source and Detector NSI parameters at the DUNE Near Detector

Alessio Giarnetti, Davide Meloni

摘要:

我们研究了DUNE近探测器(ND)对描述中微子产生($\varepsilon_{αβ}^s$)和中微子探测($\varepsilon_{αβ}^d$)的非标准相互作用参数(NSI)的约束能力。我们表明,DUNE ND能够拒绝大部分的参数空间所允许的DUNE远探测器分析,并设置最严格的界限,从加速器中微子实验$|\varepsilon_{μe}^{s,d}|$宽的相关阶段的间隔。我们还提供了对我们的结果的简单分析理解以及对其对系统误差的依赖性的数值研究,表明DUNE ND提供了一个研究源和探测器NSI的干净环境。

英文摘要:

We investigate the capability of the DUNE Near Detector (ND) to constrain Non Standard Interaction parameters (NSI) describing the production of neutrinos ($\varepsilon_{αβ}^s$) and their detection ($\varepsilon_{αβ}^d$). We show that the DUNE ND is able to reject a large portion of the parameter space allowed by DUNE Far Detector analyses and to set the most stringent bounds from accelerator neutrino experiments on $|\varepsilon_{μe}^{s,d}|$ for wide intervals of the related phases. We also provide simple analytic understanding of our results as well as a numerical study of their dependence on the systematic errors, showing that the DUNE ND offers a clean environment where to study source and detector NSI.
