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.

Little-Bang and Femto-Nova in Nucleus-Nucleus Collisions
本文从理论和实验两个方面对热致密QCD物质的研究现状进行了综述。本文回顾了束流能量扫描(Beam Energy Scan)程序在QCD相图中的应用,并介绍了QCD临界点、重子密度区粒子产生、超核产生以及核-核碰撞中全局极化效应的研究现状。奇异区的实验数据表明,高能碰撞下热模型中的巨正则态向低能正则系综态过渡。我们进一步讨论了未来的核碰撞探测重子丰富的物质的性质的前景。在高温和低重子密度下产生的夸克-胶子等离子体被称为“小爆炸”,类似地,在较低碰撞能量下富含重子的物质的飞秒级爆炸可以被称为“飞秒新星”,其可能维持非迎面碰撞的大量涡度和磁场。
