本文件介绍了将KEK的全主动、精细分段跟踪探测器SciBar引入FNAL助推器中微子束（BNB）线的物理情况。这一独特的机会是随着2005年K2 K光束业务的终止而出现的。当时，SciBar探测器可用于其他中微子束线，包括自2002年底以来一直为MiniBooNE实验提供中微子的BNB。可以用SciBar/BNB完成的物理可以分为三类，每一类都涉及几个测量。首先是中微子截面测量，这本身就很有趣，包括对多粒子最终状态的分析，具有前所未有的统计数据。其次是测量代表即将到来的T2 K实验的信号和主要背景通道的过程。第三是改善现有或计划的MiniBooNE分析和BNB的理解，无论是在中微子和反中微子模式的测量。对于这些建议的测量中的每一个，SciBar/BNB组合都提供了一个独特的机会，或者由于几个原因将显着改善当前或不久的将来的实验。首先，SciBar的精细粒度允许使用MiniBooNE检测器无法详细重建最终状态。此外，BNB中微子能谱与预期的T2 K能谱更接近，在该区域中，横截面预计会随能量发生显着变化。因此，SciBar/BNB组合将提供与MINERvA互补的能量范围内的横截面测量，并在即将到来的离轴实验中完成整个能量范围内的中微子横截面知识。«少
This document presents the physics case for bringing SciBar, the fully active, finely segmented tracking detector at KEK, to the FNAL Booster Neutrino Beam (BNB) line. This unique opportunity arose with the termination of K2K beam operations in 2005. At that time, the SciBar detector became available for use in other neutrino beam lines, including the BNB, which has been providing neutrinos to the MiniBooNE experiment since late 2002. The physics that can be done with SciBar/BNB can be put into three categories, each involving several measurements. First are neutrino cross section measurements which are interesting in their own right, including analyses of multi-particle final states, with unprecedented statistics. Second are measurements of processes that represent the signal and primary background channels for the upcoming T2K experiment. Third are measurements which improve existing or planned MiniBooNE analyses and the understanding of the BNB, both in neutrino and antineutrino mode. For each of these proposed measurements, the SciBar/BNB combination presents a unique opportunity or will significantly improve upon current or near-future experiments for several reasons. First, the fine granularity of SciBar allows detailed reconstruction of final states not possible with the MiniBooNE detector. Additionally, the BNB neutrino energy spectrum is amore » close match to the expected T2K energy spectrum in a region where cross sections are expected to vary dramatically with energy. As a result, the SciBar/BNB combination will provide cross-section measurements in an energy range complementary to MINERvA and complete the knowledge of neutrino cross sections over the entire energy range of interest to the upcoming off-axis experiments.« less
