Experimental Hadron, Photon and Lepton Research Using Calorimetric Spectrometers (Physics)

本研究项目由两大科学任务组成：1)在康奈尔电子存储环加速器（CESR）完成CUSB-II厄普西隆光谱研究。2)在费米实验室完成D0探测器的建设并开始数据采集。这个小组与哥伦比亚大学的一个小组合作（CUSB-II），在研究由“b夸克”和“反b夸克”组成的原子（upsilon）方面一直处于世界领先地位。b夸克是已知最重的夸克，大约是质子的5倍重。对这些“原子”的研究提供了关于b夸克之间强作用力的详细信息。D0实验是费米实验室20多个机构共同努力的成果。研究活动是在费米实验室的质子-反质子对撞机的D0交点区域的粒子探测系统的开发，并在物理测量中使用。该探测器系统有望成为未来十年基本粒子物理研究中最重要的仪器之一。DO探测器将用于测量弱核力载体“弱玻色子”的性质；研究强核力的性质（量子色动力学）；寻找尚未被发现的现象。研究领域是实验基本粒子物理学。这项研究研究了非常高能量下物质的基本组成部分（如电子、正电子、夸克和弱玻色子）。实验使用加速器（对撞机）提供实验室制造的最高能量粒子。数据的收集和分析使用高度复杂和精密的仪器和技术。

This research program is made up of two major scientific missions: 1) The completion of the CUSB-II Upsilon Spectroscopy studies at Cornell Electron Storage Ring accelerator, CESR. 2) Complete construction and begin data taking with the D0 detector at Fermilab. This group, in collaboration (CUSB-II) with a group from Columbia University, have been the world leaders in studies of atoms (upsilon) made up of a "b quark" and an "anti b quark". The b quark is the heaviest quark known and is approximately five times as heavy as the proton. Studies of these "atoms" provide detailed information about the strong forces between b quarks. The D0 experiment is a large collaborative effort amongst more than twenty institutions working together at Fermilab. The research activity is the development, and use in physics measurements, of a particle detector system for the D0 intersection region of the proton-antiproton collider at Fermilab. This detector system is expected to be one of the most important instruments for elementary particle physics research during the next decade. The DO detector will be used to measure the properties of the "weak bosons", carriers of the weak nuclear force; study the properties of the strong nuclear force (quantum chromodynamics); and search for yet undiscovered phenomena. The field of research is that of experimental elementary particle physics. This research studies the basic building blocks of matter (e.g., electrons, positrons, quarks, and weak bosons) at very high energies. The experiments use accelerators (colliders) which provide the highest energy particles made in the laboratory. The data is collected and analyzed using highly complex and sophisticated apparatus and techniques.
