Heavy Flavor Physics with FOCUS and BTeV

这项提案要求范德比尔特大学的一个小组支持一个基于几个重夸克实验的实验基本粒子物理学的研究和教育计划。他们正在完成费米实验室的Focus实验，为第二代B工厂实验BTeV做准备，也是在费米实验室，并考虑在康奈尔大学开展CLEO-C工作。重味物理产生了关于强相互作用和电弱相互作用、夸克混合和CP不对称的信息，并可能导致关于宇宙中物质-反物质不对称的来源的线索，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，在半导体和强子衰变中寻找D0‘D0混合，寻找稀有和被禁止的魅力衰变，研究魅力重子光谱和半轻子魅力衰变。BTeV是一台Tevatron对撞机实验，它将研究魅力和美丽衰变，以对抗标准模型对B0和BS介子、BS混合和稀有B衰变中CP破坏的解释。CLEO-c计划包括在VS=3-5GeV CM能量范围内对Charm和QCD物理的精确测量。

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.
