Neutrinos (meaning: "Small neutral ones") are elementary particles that often travel close to the speed of light, lack an electric charge, are able to pass through ordinary matter almost undisturbed and are thus extremely difficult to detect. Neutrinos have a minuscule, but nonzero mass. They are usually denoted by the Greek letter nu. Most neutrinos passing through the Earth emanate from the Sun, and more than 50 trillion solar electron neutrinos pass through the human body every second. Neutrinos are most often created or detected with a well defined flavor (electron, muon, tau). However, in a phenomenon known as neutrino flavor oscillation, neutrinos are able to oscillate between the three available flavors while they propagate through space.In this RUI project, Professor Tagg and two undergraduate research assistants at Otterbein College will continue research on neutrino oscillations with the MINOS long-baseline neutrino oscillation experiment and begin research on the MINERíA neutrino-nucleus cross-section experiment. MINOS is the flagship U.S. experiment on neutrino oscillations for the next several years. MINERvA is a valuable and opportunistic component of the future NuMI program that will coordinate with NOvA to make measurements of inclusive and exclusive neutrino-nucleus cross sections with the NOvA beam line with a fine-grained scintillation detector and the NOvA near detector. Objectives include nuclear structure measurements via a weak probe justified both on intrinsic interest and to help interpret current and future experiments. Marvin GoldbergPOMPS/PHY/EPP

中微子（意思是：小中性粒子（英语：Small neutral ones）是一种基本粒子，通常以接近光速的速度运动，不带电荷，能够几乎不受干扰地穿过普通物质，因此极难检测。中微子的质量很小，但不为零。通常用希腊字母nu表示。 大多数穿过地球的中微子来自太阳，每秒有超过50万亿个太阳电子中微子穿过人体。 中微子通常是以一种定义明确的味道（电子，μ子，τ）产生或检测到的。在RUI项目中，Tagg教授和Otterbein学院的两名本科生研究助理将通过MINOS长基线中微子振荡实验继续研究中微子振荡，并开始MINERíA中微子-原子核截面实验的研究。 MINOS是未来几年美国中微子振荡的旗舰实验。MINERvA是未来NuMI计划的一个有价值和机会性的组成部分，它将与NOvA协调，利用NOvA束线和细颗粒闪烁探测器和NOvA近探测器测量包容性和排他性的中微子核截面。目标包括通过弱探针进行核结构测量，这既符合内在兴趣，又有助于解释当前和未来的实验。Marvin Goldberg POMPS/PHY/EPP
