This project involves the experimental study of the properties of strongly interacting particles of matter known as hadrons. These hadrons which include protons, neutrons, and mesons, as well as their excitations, are what atomic nuclei are composed of, and constitute about 99% of all ordinary matter on Earth. The hadrons themselves are composed of quarks and strong energy called gluons. Surprisingly, we do not yet know how quarks and gluonic energy are arranged to produce the properties of prosaic matter. Our research group will study quark and gluonic properties of hadrons and their excitations using primarily the new high precision superconducting electron accelerator CEBAF at Jefferson Laboratory. in preparation for these experiments, we had been working for many years on the design and construction of large particle detectors using the leading edge technology. Several graduate students will obtain Ph.D. degrees based on these experiments, and many undergraduates will obtain hands on experience with modern technology.

该项目涉及对强相互作用物质粒子（称为强子）的性质进行实验研究。 这些强子包括质子、中子和介子，以及它们的激发态，是原子核的组成部分，构成了地球上所有普通物质的99%。 强子本身由夸克和称为胶子的强能量组成。 令人惊讶的是，我们还不知道夸克和胶子能量是如何排列的，以产生质子物质的性质。 我们的研究小组将主要利用杰斐逊实验室的新的高精度超导电子加速器CEBAF研究强子的夸克和胶子性质及其激发。 为准备这些实验，我们多年来一直致力于利用尖端技术设计和建造大粒子探测器。 一些研究生将获得博士学位。许多本科生将获得现代技术的实践经验。
