项目摘要

The three major research activities of this group are all centered at the Fermi National Accelerator Laboratory (Fermilab). The activities are: 1) The CDF experiment which is currently the major experiment at the proton-antiproton collider at Fermilab. This collider produces the highest (by a factor of three) energy collisions available in the world. The CDF detector system is one of the most important instruments for elementary particle physics research at present. It is being 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 phenomena not observable at the previously accessible lower energies. 2) A study of the violation of the fundamental symmetry, CP, in the decay of the short lived neutral K meson. 3) A measurement of the magnetic moment of the omega minus baryon (made up of three strange quarks). 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 (and 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.

该小组的三大研究活动均为费米国家加速器实验室（Fermilab）. 这些活动是： 1)CDF实验是目前主要的在费米实验室的质子-反质子对撞机上进行实验。这对撞机产生的能量最高（三倍）世界上最大的碰撞。 CDF探测器系统是研究基本粒子的最重要的仪器之一物理学研究目前它被用来衡量 “弱玻色子”的性质，弱核的载体力;研究强核力的性质（量子色动力学）;并寻找现象不在先前可获得的较低能量下可观察到。 2)对基本对称性破坏的研究， CP在短寿命中性K介子衰变中的作用。 3)欧米茄磁矩的测量负重子（由三个奇怪的夸克组成）。研究领域是实验小学粒子物理学本研究主要研究基础建筑物质块（例如，电子、正电子、夸克和弱玻色子）在非常高的能量。实验使用提供最高能量的加速器（和对撞机）在实验室里制造的粒子。收集数据，使用高度复杂和精密的仪器进行分析，技术.
