中文摘要
SENSE促进了欧洲、美国、巴西和俄罗斯研究人员在高强度前沿中微子物理领域最重要的研究项目中的合作。对中微子振荡的观察建立了一幅与三种中微子口味在三种质量特征态和小质量差异中混合一致的图像。实验异常表明存在惰性中微子态参与混合而不与SM规范玻色子耦合。轻子混合和大质量中微子为轻子领域的标准模型偏差提供了一个入口,包括带电轻子味违反。FNAL短基线中微子(SBN)项目基于三个几乎相同的液体氩气时间投影室,沿着助推器中微子束,提供了一个令人信服的机会来解决异常现象,并通过出现和消失振荡搜索在eV质量尺度上对无菌中微子进行最灵敏的搜索。MicroBooNE、ICARUS和SBND将通过比较在距离源不同距离处测量到的中微子事件光谱来寻找振荡信号。FNAL SBN项目是全球中微子物理界在实现深地下中微子实验(DUNE)方面的重要一步,它将为中微子质量有序的确定、CP违和的测量、使用长基线风味跃变的三风味振荡范式的精确测试、在多信使天文学的框架中寻找核子衰变和研究核坍缩超新星的中微子爆发。SENSE研究人员为SBN和DUNE项目做出了重大贡献,并将在探测器的调试、数据采集和分析方面发挥主导作用。这些努力促进了尖端技术的发展,并在粒子物理之外产生了副产品。
英文摘要
SENSE promotes the collaboration among European, American, Brazilian and Russian researchers involved in the most important research projects in the field of neutrino physics at the high intensity frontier. The observation of neutrino oscillations established a picture consistent with the mixing of three neutrino flavours in three mass eigenstates and small mass differences. Experimental anomalies suggest the existence of sterile neutrino states participating in the mixing and not coupling to the SM gauge bosons. Lepton mixings and massive neutrinos offer a gateway to deviations from the Standard Model in the lepton sector including Charged Lepton Flavour Violation. The FNAL Short-Baseline Neutrino (SBN) program based on three almost identical liquid argon Time Projection Chambers located along the Booster Neutrino Beam offers a compelling opportunity to resolve the anomalies and performthe most sensitive search for sterile neutrinos at the eV mass scale through appearance and disappearance oscillation searches. MicroBooNE, ICARUS and SBND will search for the oscillation signal by comparing the neutrino event spectra measured at different distances from the source. The FNAL SBN program is a major step towards the global effort of the neutrino physics community in realising the Deep Underground Neutrino Experiment (DUNE) which will provide fundamental contribution to the determination of neutrino mass ordering, measurement of CP violation, precision tests of the three-flavor oscillation paradigm using long-baseline flavor transition, search for nucleon decay and study of the burst of neutrinos from core-collapse supernova in the framework of multi-messenger astronomy. SENSE researchers have provided major contributions to the SBN and DUNE projects and will take leading roles in the commissioning of the detectors, data taking and analysis. These endeavors foster the development of cutting edge technologies with spin-offs outside particle physics.
