This award will provide support to a group from Southeastern Massachusetts University, who is working on an experiment (E850) at Brookhaven National Laboratory, designed to improve our understanding of the structure of hadrons and the nature of the dynamics of their interactions at short distances. The experimental method is based on observing two- body elastic scattering and production processes, when they occur at 90o in the center of mass. This experiment will test Quantum Chromodynamics (QCD) by establishing the limits of validity of perturbative methods in QCD and achieving some understanding of the nature of the non-pertubative contributions.

该奖项将为东南马萨诸塞大学的一个小组提供支持，该小组正在布鲁克海文国家实验室进行一项实验（E850），旨在提高我们对强子结构及其短距离相互作用动力学性质的理解。 该实验方法基于观察二体弹性散射和产生过程，当它们发生在质心 90° 时。 该实验将通过确定 QCD 中微扰方法的有效性极限来测试量子色动力学 (QCD)，并对非微扰贡献的本质进行一些了解。
