After decades of study it is safe to say that the nuclearinteraction, ie. the interaction between quarks, is well understood. However the manifestations of this interaction in nuclear matter (hadrons) isonly understood in the narrowest of settings. Quark confinement and the structure of hadrons remain intriguing puzzles. Our proposal willstudy these questions in two broad programs:1) We have identified a few new states that do not fit into thesimple pictures of hadron structure. Other states of this type will beidentified and their decay properties will be measured.2) Electron induced reactions will be used to study the proton andother baryons. Hard-scattering experiments will reveal the quarkstructure of these states.

经过几十年的研究，可以肯定地说，核相互作用，即。夸克之间的相互作用，已经被很好地理解了。 然而，这种相互作用在核物质（强子）中的表现形式只有在最西方的环境中才能理解。 夸克禁闭和强子的结构仍然是令人感兴趣的谜。 我们的建议将在两个广泛的计划中研究这些问题：1）我们已经确定了一些新的状态，它们不适合强子结构的简单图像。 2）电子诱导反应将被用来研究质子和其他重子。 硬散射实验将揭示这些态的夸克结构。
