Measurement of threshold charged pion production will be carried out for proton-proton scattering, including spin degrees of freedom, in order to explore model dependencies of the fundamental reaction mechanisms. This work will be done at the internal target facility of the Indiana University Cyclotron Facility. In addition, work on the important inner tracking chamber of the CEBAF large acceptance detector will be carried out. The latter is in support of an approved experiment at CEBAF for which this Pitt group is the lead group. In this activity, the quark sub-structure of nucleon resonances will be probed through their momentum transfer dependence.

将对质子-质子散射（包括自旋自由度）进行阈值带电π介子产生的测量，以探索基本反应机制的模型依赖性。 这项工作将在印第安纳大学回旋加速器设施的内部目标设施中完成。 此外，CEBAF大型接收探测器重要的内跟踪室的工作也将进行。 后者支持 CEBAF 批准的一项实验，皮特小组是该实验的牵头小组。 在本次活动中，将通过动量转移依赖性来探究核子共振的夸克子结构。
