Intermediate Energy Nuclear Physics

该奖项是根据2009年美国复苏和再投资法案（公法111 - 5）资助的。该基金支持的物理计划旨在研究核子的自旋和风味结构。研究将在德国的DESY实验室进行，作为爱马仕合作的一部分，并在芝加哥附近的费米国家实验室作为E906合作的一部分。爱马仕的主要重点是通过测量极化电子在极化目标上的散射来确定夸克和胶子对质子和中子的固有角动量的贡献。E906计划的重点是Drell/Yan双μ子对的产生，以确定核子海中的反夸克分布。此外，该小组将领导液氢和氘靶的开发和操作，作为他们对这一新努力的硬件责任的一部分。随着E906的活动将增加，该集团对爱马仕的努力将相应减少。 本科生和研究生以及博士后学者的教育和培训，以及针对公众的推广活动是本研究计划的一个重要方面。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The physics program supported by this grant is directed at the study of spin and flavor structure of nucleons. Research will be carried out at the DESY laboratory in Germany as part of the HERMES collaboration, and at the Fermi National Laboratory near Chicago as part of the E906 collaboration. The main focus with HERMES will be to determine the contribution of quarks and gluons to the intrinsic angular momentum of the proton and neutron by measuring the scattering of polarized electrons on polarized targets. The program with E906 is focused on Drell/Yan production of di-muon pairs to determine the antiquark distribution in the nucleon sea. In addition, the group will lead the development and operation of the liquid hydrogen and deuterium targets as part of their hardware responsibility for this new effort. As activities on E906 will ramp up, the group's efforts on HERMES will ramp down accordingly. Education and training of both, undergraduate and graduate students, and postdoctoral scholars, as well as outreach aimed at the general public is an important aspect of this research program.
