我们报告的纵向强度在核子共振区的详细研究，提出了新的结果，包括电子-质子截面测量在杰斐逊实验室大厅C在四动量转移范围。这些数据已被用来准确地执行167 Rosenbluth型纵向/横向分离。这里给出了精度数据，沿着给出了非弹性结构函数的第一个分离值，并在此范围内。共振的纵向分量被发现是显着的，无论是在幅度和定义的质量峰的存在。此外，在分离的结构函数上独立地观察到夸克-强子对偶性。
We report on a detailed study of longitudinal strength in the nucleon resonance region, presenting new results from inclusive electron-proton cross sections measured at Jefferson Lab Hall C in the four-momentum transfer range. The data have been used to accurately perform 167 Rosenbluth-type longitudinal/transverse separations. The precisiondata are presented here, along with the first separate values of the inelastic structure functionsandin this regime. The resonance longitudinal component is found to be significant, both in magnitude and in the existence of defined mass peaks. Additionally, quark-hadron duality is here observed abovein the separated structure functions independently.
