中文摘要
SENSE促进欧洲、美国、巴西和俄罗斯研究人员在高强度前沿中微子物理学领域最重要的研究项目中的合作。中微子振荡的观测建立了一个与三种中微子味在三个质量本征态和小质量差中混合一致的图像。实验异常表明,存在无菌中微子状态参与混合,而不是耦合到SM规范玻色子。轻子混合和大质量中微子提供了在轻子部分偏离标准模型的途径,包括带电轻子味违反。FNAL短基线中微子(SBN)计划的基础上,三个几乎相同的液体氩时间投影室位于沿着助推中微子束提供了一个令人信服的机会,解决异常和执行最灵敏的搜索无菌中微子在eV质量尺度通过出现和消失振荡搜索。MicroBooNE、ICARUS和SBND将通过比较在离源不同距离处测量的中微子事件谱来搜索振荡信号。FNAL SBN计划是中微子物理界在实现深层地下中微子实验(DUNE)方面的全球努力的重要一步,该实验将为确定中微子质量排序,测量CP破坏,使用长基线味道跃迁的三味振荡范式的精度测试,在多信使天文学的框架下寻找核子衰变和研究核心坍缩超新星的中微子爆发。SENSE的研究人员为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,并在粒子物理学之外产生了副产品。
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.
