论文摘要
Orca（在深渊中使用宇宙的振荡研究）是KM3NET的低能节点，KM3NET是地中海中的下一代水下Cherenkov Neutrino检测器。 KM3NET-ORCA的主要目标是确定中微子质量排序（NMO）。 KM3NET-ORCA具有很少的GEV的能量阈值和有效的几个MTON，也可以对大气振荡参数进行精确测量。此外，它进入广泛的能量和基线的途径使得在标准模型（例如中微子的非标准相互作用（NSI））之外发现外来物理学是最佳的。提出了检测器对中微子质量排序的敏感性，以及确定大气振荡参数的潜力。据观察，KM3NET-ORCA将在数据获取三年后通过数量级来改善NSI参数的当前上限。
ORCA (Oscillations Research with Cosmics in the Abyss) is the low-energy node of KM3NeT, the next generation underwater Cherenkov neutrino detector in the Mediterranean sea. The primary goal of KM3NeT-ORCA is the determination of the neutrino mass ordering (NMO). With an energy threshold of few GeV and an effective mass of several Mtons, KM3NeT-ORCA can also make precision measurements of atmospheric oscillation parameters. Moreover, its access to a wide range of energies and baselines makes it optimal to discover exotic physics beyond the Standard Model such as Non-Standard Interactions (NSI) of neutrinos. The sensitivity of the detector to the neutrino mass ordering is presented, along with its potential for determination of the atmospheric oscillation parameters. It is observed that KM3NeT-ORCA will improve the current upper limits on NSI parameters by an order of magnitude after three years of data taking.
