AI中文摘要:

NOvA是一项长基线中微子振荡实验,旨在研究轻子扇区的中微子混合参数、质量顺序和CP破坏。该实验成功的一个关键组成部分是对与探测器响应和校准相关的系统不确定性的稳健理解。为解决这一问题,NOvA在费米实验室测试束设施部署了一项测试束实验,该实验从2019年4月到2022年7月收集数据。NOvA测试束实验使用了一个30吨的分段液体闪烁体探测器,其功能与NOvA近探测器和远探测器完全相同,用于分析p-Cu碰撞产生的标记粒子,其仪器能够选择和识别动量范围为0.4-1.5GeV/c的电子、μ子、π介子、K介子和质子。对收集数据的分析提供了对影响NOvA分析的最大系统不确定性的更好理解,这些不确定性包括探测器响应、能量校准以及强子和电磁能量分辨率。

英文摘要:

NOvA is a long-baseline neutrino oscillation experiment designed to study the neutrino mixing parameters, mass ordering, and CP violation in the lepton sector. A key component of the success of the experiment is a robust understanding of the systematic uncertainties associated with detector response and calibration. To address this, NOvA deployed a Test Beam experiment at the Fermilab Test Beam Facility, which collected data from April 2019 through July 2022. The NOvA Test Beam experiment used a 30-ton segmented liquid scintillator detector functionally identical to the NOvA Near and Far Detectors to analyze tagged particles produced from p-Cu collisions, with instrumentation capable of selecting and identifying electrons, muons, pions, kaons, and protons with momentum ranging from 0.4-1.5GeV/c. Analysis of the collected data provides a better understanding of the largest systematic uncertainties impacting NOvA's analyses, which include the detector response, energy calibration, and hadronic and electromagnetic energy resolutions.
