Heavy Flavor Physics with FOCUS and BTeV

该提案要求支持范德比尔特大学的一个小组，以几个重夸克实验为基础，开展实验基本粒子物理学的研究和教育计划。他们正在费米实验室完成FOCUS实验，为BTeV做准备，BTeV是第二代B工厂实验，也在费米实验室，并考虑在康奈尔大学从事CLEO-c工作。重味物理学提供了有关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，并可能导致有关宇宙中物质-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是一个固定目标的粲产生实验，寻找半电子和强子衰变中的D 0 `D 0混合，寻找罕见的和禁止的粲衰变，研究粲重子谱和半轻子粲衰变。BTeV是一个Tevatron对撞机实验，将研究魅力和美丽的衰变，以面对标准模型解释的CP违反在B 0和Bs介子，Bs混合和罕见的B衰变。CLEO-c计划包括在vs = 3-5 GeV CM能量范围内精确测量粲和QCD物理。

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.
