论文摘要
在ADS/QCD的硬壁模型的框架中研究了核子之间的过渡和激发状态之间过渡状态的电磁过渡形式。介绍了大部分ADS空间中旋转器和向量场的轮廓函数。使用批量和边界理论中的生成函数之间的AD/CFT对应关系，从光子和核子场之间相互作用的批量作用中获得了过渡形式因子的表达。我们考虑R（1710，1535，1440）\ rightarrow n过渡，并绘制Dirac和Pauli形式依赖性对转移动量正方形的依赖性。同样，提出了这些过渡的螺旋振幅。
The electromagnetic transition form factors for the transition between the ground and excited states of nucleons are studied in the framework of the hard-wall model of AdS/QCD. The profile functions of the spinor and vector fields in the bulk of AdS space are presented. Using AdS/CFT correspondence between the generating functions in the bulk and boundary theories an expression for the transition form factors are obtained from the bulk action for the interaction between the photon and nucleon fields. We consider the R(1710, 1535, 1440)\rightarrow N transitions and plot the Dirac and Pauli form factor dependencies on transferred momentum square. Also, the spiral amplitudes for these transitions are presented.
