CAREER: Valence and Sea Quark Dynamics at Fermilab

质子是日常物质的组成部分之一，每个原子的核心都有质子。质子又是由称为夸克和胶子的亚核粒子组成的。该奖项支持的项目将提高我们对质子内部结构的理解，重点放在组成夸克的动力学行为上。费米国家加速器实验室(Fermilab)的高能粒子加速器设施将用于进行这项研究。一束质子将加速到高能，并击中液氢靶；氢原子的原子核由一个质子组成。对碰撞中产生的粒子的测量将提供有关夸克在其母质子中的行为的信息。该奖项支持的努力还将有助于增加受过核物理学家培训的年轻科学家的多样性。培训下一代核物理学家对于保持与国家能源和国防需求相关的专业知识以及继续推进核物理和技术方面的应用和非应用研究至关重要。在该奖项的每一年，一名来自曼霍利奥克学院的学生将有机会在费米实验室进行夏季核物理研究。此外，该奖项还将为一名非裔美国研究生提供学费、工资和旅行补贴。除了支持他的论文研究，他还将得到资助，每学期去他的母校霍华德大学一次，与现在的物理学本科生谈论他在攻读核物理博士学位方面的经历和进展。霍华德大学是一所历史悠久的黑人大学。

The proton is one of the building blocks of everyday matter, with protons in the core of every atom. The proton is in turn made of subnuclear particles known as quarks and gluons. The project supported by this award will improve our understanding of the proton's internal structure, with a focus on the dynamical behavior of the constituent quarks. High-energy particle accelerator facilities at Fermi National Accelerator Laboratory (Fermilab) will be used to perform the research. A beam of protons will be accelerated to high energy and strike a liquid hydrogen target; the nucleus of a hydrogen atom is comprised of a single proton. Measurement of the particles produced in the collisions will provide information on the behavior of the quarks in their parent protons.The efforts supported by this award will additionally serve to increase diversity among young scientists trained as nuclear physicists. Training the next generation of nuclear physicists is critical to maintain expertise relevant to the nation's energy and defense needs and to continue advancing both applied and non-applied research in nuclear physics and technology. In each year of this award a student from Mount Holyoke College, an undergraduate institution for women, will be given the opportunity to perform summer research in nuclear physics at Fermilab. Furthermore, this award will provide tuition, salary, and travel support for an African-American graduate student. In addition to supporting his dissertation research, he will receive support to travel once per semester to his alma mater, Howard University, a historically black university, to speak with current physics undergraduates about his experience and progress pursuing a Ph.D. in nuclear physics.
