我们批判性地研究了在AdS/QCD对应的框架下，标量玻色子在介质Bjorken x区域中的深度非弹性散射过程的标度问题。为了得到正确的极化结构的前向电产生振幅，我们表明，一个需要添加（至少）标量标量和标量矢量强子振幅。这说明了如何从一个简单的方案的基础上AdS/QCD对应的部分子图片可能出现，提供一个允许的强子场的共形维数等于1，并使用“强子-部分子对偶”的概念。
We critically examine the question of scaling of the Deep Inelastic Scattering process in the medium Bjorken x region on a scalar boson in the framework of the AdS/QCD correspondence. To get the right polarization structure of the forward electroproduction amplitude, we show that one needs to add (at least) the scalar to scalar and scalar to vector hadronic amplitudes. This illustrates how the partonic picture may emerge from a simple scenario based on the AdS/QCD correspondence, provided one allows the conformal dimension of the hadronic field to equal 1 and use the concept of “hadron–parton duality”.
