UCLA CUORE Neutrino Physics Research Program

下一代无中微子双贝塔衰变(NDBD)实验可能为标准模型的扩展提供一个有趣的方向，包括两个单位的轻子数破坏和量子场论中不同于标准模型希格斯质量的新的Majorana质量项。如果中微子是马约拉纳粒子，它将是唯一已知的反粒子是它自己的费米子。中微子质量的绝对尺度也可以通过这样的实验来唯一地确定。这些都是现代物理学的基本问题。这一奖项将使加州大学洛杉矶分校的团队能够继续他们在Gran Sasso地下实验室进行的CUORE NDBD实验的研究计划。该实验目前正处于建设阶段，预计将于2014年底开始采集数据。加州大学洛杉矶分校的研究工作将集中在CUORE电子系统的质量保证和对背景来源的理解上。他们将负责与南卡罗来纳大学和米兰集团合作测试、安装和调试CUORE电子系统。他们将继续对CUORE-0/CUORE背景源进行蒙特卡罗模拟。广泛的影响NDBD的实验解决了基本物理问题，这些问题具有远远超出粒子和核物理的科学影响。CuORE测辐射热计探测器代表了中微子科学中探测器技术的重大进步，可能是最好的半高宽分辨率为几千电子伏特(Kev)的阿尔法探测器，可能在物理和其他应用科学的核辐射测量中有应用。他们将继续让他们的本科生和NSF-REU的学生参与研究计划，并为他们提供中微子物理和现代探测器技术的研究经验。

The next generation of neutrino-less Double Beta Decay (NDBD) experiments may provide an intriguing direction for extensions of the Standard Model, including lepton number violation by two units and a new Majorana mass term in quantum field theory unlike that of the Standard Model Higgs mass. If the neutrino is a Majorana particle, it would be the only known fermion whose anti-particle is itself. The absolute scale of neutrino masses can also be uniquely determined via such experiments. These are fundamental questions of modern physics. This award will enable the UCLA group to continue their research program in the CUORE NDBD experiment at the Gran Sasso underground laboratory. The experiment is currently in the construction phase and is expected to start data-taking by the end of 2014. The UCLA research effort will focus on the quality assurance of the CUORE electronics system and on the understanding of background sources. They will be responsible for testing, installation and commissioning of the CUORE electronics system in collaboration with the University of South Carolina and Milan groups. They will continue to work on the Monte Carlo simulations of the CUORE-0/CUORE background sources. Broad ImpactThe NDBD experiments address fundamental physics issues that have a scientific impact much beyond particle and nuclear physics. The CUORE bolometer detector represents a major advance of detector technology in neutrino sciences and is probably the best alpha detector with a FWHM resolution of a few kiloelectronvolt (keV), which may have applications in nuclear radiation measurements for physics and other applied sciences. They will continue to involve their undergraduate students and NSF-REU students in the research programs and provide them with research experiences in neutrino physics and modern detector technology.
