对一个新获得的包涵电子-核子散射数据样本进行了分析，用于夸克-强子对偶性的精度检验。数据在核子共振区，范围为0。3 < Q2 < 5.0 (GeV / c)(2)。在突出的共振增强周围的有限区域和扩展区域都观察到对偶性。较高的扭转对F2结构函数的贡献平均较小，即使在大约0.5 （GeV/c）的低Q2状态下也是如此(2)。利用对偶性，得到了平均标度曲线。在所有情况下，对偶性似乎是核子结构函数的一个非平凡性质。
A newly obtained sample of inclusive electron-nucleon scattering data has been analyzed for precision tests of quark-hadron duality. The data are in the nucleon resonance region, and span the range 0. 3<Q2<5.0 (GeV/c)(2). Duality is observed both in limited and extended regions around the prominent resonance enhancements. Higher twist contributions to the F2 structure function are found to be small on average, even in the low Q2 regime of approximately 0.5 (GeV/c)(2). Using duality, an average scaling curve is obtained. In all cases, duality appears to be a nontrivial property of the nucleon structure function.
