U.S.-Brazil Cooperative Research Project for the Fermilab FOCUS Experiment

这项美国-巴西奖支持威斯康星大学麦迪逊分校的Marleigh Sheaff博士和科罗拉多大学的John P. Cumalat博士与巴西巴西物理研究中心（CBPF）的Joao Anjos、Ignacio Bediaga、Jussara Miranda和Alberto Reis教授在基本粒子物理学领域开展合作。他们将在分析项目上合作，比如FOCUS实验（在升级光谱仪中产生魅力的照片），该实验关注魅力介子和重子的衰变，以及光子在核目标上产生魅力粒子。这个合作项目将允许美国学生前往巴西参加正在进行的合作项目FOCUS，这是伊利诺斯州巴达维亚费米实验室的一个固定目标粲夸克实验。我们在巴西的对应机构CNPq将为一名在费米实验室工作的巴西学生提供支持。通过该奖项，来自美国和巴西的研究人员在共同感兴趣的大型科学项目上进行合作，来自两国的年轻物理学家在其职业生涯的早期有在国际环境中工作的经验。

This US-Brazil award supports Dr. Marleigh Sheaff, University of Wisconsin-Madison, and Dr. John P. Cumalat, University of Colorado, to work with Professors Joao Anjos, Ignacio Bediaga, Jussara Miranda, and Alberto Reis of Centro Brasileiro de Pesquisas Fisicas (CBPF) in Rio de Janeiro, Brazil in the field of elementary particle physics. They will work together on analysis projects, such as the FOCUS experiment (Fotoproduction of Charm in an Upgraded Spectrometer), that concern decays of charm mesons and baryons and the production of charm particles by photons on nuclear targets.This collaborative project will allow U.S. students to travel to Brazil to join an on-going collaboration, FOCUS, which is a fixed target charm-quark experiment based at Fermilab in Batavia, Illinois. Our counterpart agency in Brazil, CNPq, will provide support for a Brazilian student to be based at Fermilab. Through this award researchers from both the U.S. and Brazil collaborate on large-science projects of mutual interest, and younger physicists from both countries have the experience of working in an international setting early in their careers.
