The Collider Detector at Fermilab (CDF) experiment is studying the world's highest energy proton-antiproton collisions.  The CDF collaboration consists of scientists from eleven different countries, including a group of over 20 Canadian particle physicists affiliated with the Institute of Particle Physics (IPP).  The IPP group joined CDF in 1991 for the Run I data taking period.  One of the highlights of Run I, which by all measures was a great success, was the discovery of the top quark.  The IPP group is now participating in the Tevatron Run II programme. For Run II, the CDF detector and the Tevatron collider underwent major upgrades and we anticipate a factor of 50-100 increase in the statistics of specific final states by 2009. The Tevatron and the CDF detector are performing very well with data taking efficencies near 90% and peak luminosities in excess of 1.7E32/cm^2/s.  This has allowed us to collect over 1/fb of data and an anticipated doubling of the current dataset between now and the end of next year.  The fully realized physics programme of Run II requires the analysis of inverse femtobarns of collision data.  This integrated luminosity will allow us, for example, to search for new particles and forces, to measure the top quark mass, the W boson mass, and key parameters of the observed matter-antimatter asymmetry of the universe, all with unprecedented precision. This proposal requests funding for the next three years in order for the IPP group to capitalise on NSERC's significant investment in the CDF II experiment and its physics. This will allow our graduate students, research associates, and faculty to continue their service contributions to CDF and to complete their ongoing physics analyses at a time when the most exciting physics in the history of the Tevatron programme will be analysed.

费米实验室（CDF）的对撞机探测器实验正在研究世界上能量最高的质子-反质子碰撞。CDF合作项目由来自11个不同国家的科学家组成，其中包括隶属于粒子物理研究所（IPP）的20多名加拿大粒子物理学家。IPP小组于1991年加入CDF，进行第一次数据采集期。Run I的亮点之一是发现了顶夸克，从各个方面来看，它都是一个巨大的成功。IPP小组目前正在参加Tevatron Run II方案。对于Run II， CDF探测器和Tevatron对撞机进行了重大升级，我们预计到2009年具体最终状态的统计数据将增加50-100倍。Tevatron和CDF探测器表现非常好，数据采集效率接近90%，峰值光度超过1.7E32/cm^2/s。这使我们能够收集超过1/fb的数据，预计从现在到明年年底，当前数据集将翻一番。Run II的完全实现的物理程序需要对碰撞数据的逆飞波进行分析。例如，这种集成的光度将使我们能够搜索新的粒子和力，测量顶夸克质量，W玻色子质量，以及观测到的宇宙物质-反物质不对称性的关键参数，所有这些都具有前所未有的精度。该提案要求在未来三年提供资金，以便IPP小组利用NSERC在CDF II实验及其物理方面的重大投资。这将使我们的研究生、研究助理和教职员工能够继续为CDF做出贡献，并在分析Tevatron项目历史上最激动人心的物理时完成他们正在进行的物理分析。
