NOvA实验的现状与展望

The NOvA Experiment: Status and Outlook

R. B. Patterson

摘要:

NOvA长基线中微子振荡实验目前正在建设中,将使用费米实验室升级的NuMI中微子源和明尼苏达州阿什河的14千吨探测器来探索中微子部门。NOvA采用高活性、精细分段的探测器设计,提供了极好的事件识别能力,允许精确测量ν_e/ν_e-条出现和ν_μ/ν_μ-条消失,NOvA将通过该测量提供对θ_13,θ_23,|Δm^2_atm|中微子质量等级和CP破坏相δ。在这篇文章中,我们回顾了NOvA独特的广泛的物理范围,包括根据θ_13的最新知识进行的灵敏度更新,并讨论了实验的构造和操作时间轴。

英文摘要:

The NOvA long-baseline neutrino oscillation experiment is currently under construction and will use an upgraded NuMI neutrino source at Fermilab and a 14-kton detector at Ash River, Minnesota to explore the neutrino sector. NOvA uses a highly active, finely segmented detector design that offers superb event identification capability, allowing precision measurements of ν_e/ν_e-bar appearance and ν_μ/ν_μ-bar disappearance, through which NOvA will provide constraints on θ_13, θ_23, |Δm^2_atm|, the neutrino mass hierarchy, and the CP-violating phase δ. In this article, we review NOvA's uniquely broad physics scope, including sensitivity updates in light of the latest knowledge of θ_13, and we discuss the experiment's construction and operation timeline.
