摘要:

随着短基线(SBL)中微子/反中微子振荡的实验结果以及最近仔细重新计算的核反应堆反中微子通量,几个唯象模型中的紧张关系不断增加。在一个翻新的SBL CERN-PS设施中,基于超纯低温液态氩(LAr)成像技术,提出了一项旨在解决开放问题的实验[1]。受此情景的启发,进行了详细的物理案例研究。我们处理了特定的物理模型,并通过完整的模拟优化了中微子束。还研究了LAr探测未完全涵盖的实验方面,即在逐事件基础上测量轻子电荷及其在宽范围内的能量。事实上,从带电电流(CC)(反)中微子相互作用的μ子轻子在解开不同的现象学的情况下,他们的电荷状态是确定的重要作用。此外,μ子的出现/消失的研究可以受益于大量的统计CC μ子事件从初级中微子束。我们的研究结果详细报告在这个建议。我们的目标是设计,建造和安装两个光谱仪在“近”和“远”的SBL CERN-PS网站,兼容已经提出的LAr探测器。利用这两台光谱仪的大质量,还开发了它们的独立性能。

英文摘要:

Tensions in several phenomenological models grew with experimental results on neutrino/antineutrino oscillations at Short-Baseline (SBL) and with the recent, carefully recomputed, antineutrino fluxes from nuclear reactors. At a refurbished SBL CERN-PS facility an experiment aimed to address the open issues has been proposed [1], based on the technology of imaging in ultra-pure cryogenic Liquid Argon (LAr). Motivated by this scenario a detailed study of the physics case was performed. We tackled specific physics models and we optimized the neutrino beam through a full simulation. Experimental aspects not fully covered by the LAr detection, i.e. the measurements of the lepton charge on event-by-event basis and their energy over a wide range, were also investigated. Indeed the muon leptons from Charged Current (CC) (anti-)neutrino interactions play an important role in disentangling different phenomenological scenarios provided their charge state is determined. Also, the study of muon appearance/disappearance can benefit of the large statistics of CC muon events from the primary neutrino beam. Results of our study are reported in detail in this proposal. We aim to design, construct and install two Spectrometers at "NEAR" and "FAR" sites of the SBL CERN-PS, compatible with the already proposed LAr detectors. Profiting of the large mass of the two Spectrometers their stand-alone performances have also been exploited.
