轻子与核子散射中的夸克-强子对偶性

Quark-hadron duality in lepton scattering off nucleons

Krzysztof M. Graczyk

摘要:

用共振夸克模型研究了轻子与核子散射中的夸克-强子(QH)对偶性。结果表明,在中微子散射的情况下,带电和中性电流$xF_1^{νN}$、$F_2^{νN}$和$xF_3^{νN}$弱结构函数同时具有对偶性.我们证明,QH对偶性可以是有用的属性,在所谓的共振区的结构功能建模。作为一个例子,它表明,结合相对论夸克模型的预测与对偶参数允许建设的包容性共振$F_2^{ep}$结构功能。

英文摘要:

Quark-hadron (QH) duality in lepton scattering off nucleons is studied with the resonance quark model. It is shown that in the case of neutrino scattering off an isoscalar target the duality is simultaneously observed for charged and neutral currents $xF_1^{νN}$, $F_2^{νN}$, and $xF_3^{νN}$ weak structure functions. We demonstrate that the QH duality can be useful property for modeling structure functions in the so-called resonance region. As an example it is shown that combining relativistic quark model predictions with duality arguments allows a construction of the inclusive resonance $F_2^{ep}$ structure function.
