This proposal requests support for a group at Vanderbilt University for a program of research and education in experimental elementary particle physics based on several heavy quark experiments. They are finishing up the FOCUS experiment at Fermilab, preparing for BTeV, a second-generation B-factory experiment, also at Fermilab and considering working on CLEO-c at Cornell. Heavy flavor physics yields information about the strong and electroweak interactions, quark mixing and CP asymmetry and may lead to hints concerning the source of the matter-antimatter asymmetry in the universe, one of the most fundamental questions in science. FOCUS is a fixed-target, charm production experiment searching for D0`D0 mixing in semielectronic and hadronic decays, searching for rare and forbidden charm decays, studying charm baryon spectroscopy and semileptonic charm decays. BTeV is a Tevatron collider experiment that will study charm and beauty decays in order to confront the Standard Model explanation of CP violation in B0 and Bs mesons, Bs mixing and rare b decays. The CLEO-c program includes precision measurements of charm and QCD physics in the vs = 3-5 GeV CM energy range.

该提案要求范德比尔特大学的一个小组支持基于几个重夸克实验的实验基本粒子物理研究和教育计划。他们正在费米实验室完成 FOCUS 实验，为同样在费米实验室进行的第二代 B-factory 实验 BTeV 做准备，并考虑在康奈尔大学开展 CLEO-c 实验。浓重的物理学产生了关于强相互作用和电弱相互作用、夸克混合和CP不对称性的信息，并可能带来有关宇宙中物质-反物质不对称性来源的线索，这是科学中最基本的问题之一。 FOCUS 是一个固定目标的魅力产生实验，寻找半电子和强子衰变中的 D0`D0 混合，寻找罕见和禁止的魅力衰变，研究魅力重子光谱和半轻子魅力衰变。 BTeV 是一项 Tevatron 对撞机实验，将研究魅力和美丽衰变，以对抗 B0 和 Bs 介子、Bs 混合和罕见 b 衰变中 CP 破坏的标准模型解释。 CLEO-c 计划包括对 vs = 3-5 GeV CM 能量范围内的魅力和 QCD 物理的精确测量。
