Experimental Research in Elementary Particle Physics

该组的三大研究活动均以费米国家加速器实验室（Fermilab）为中心。主要活动有：1)CDF实验，这是目前费米实验室质子-反质子对撞机的主要实验。这台对撞机产生了世界上最高（三倍）的能量碰撞。CDF探测器系统是目前基本粒子物理研究最重要的仪器之一。它被用来测量“弱玻色子”的性质，弱核力的载体；研究强核力的性质（量子色动力学）；寻找在先前可观测到的较低能量下无法观测到的现象。2)短寿命中性K介子衰变中违反基本对称性CP的研究。3)欧米茄负重子（由三个奇异夸克组成）磁矩的测量。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（和对撞机）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。

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.
