论文摘要
这项工作从轻单量子场理论中的理论观点研究了BESIII的两光子过程的实验。我们通过两种形式的Brodsky-huang-Lepage〜（bhl）处方和轻锥全息QCD采用触发形式的动量空间波函数。我们发现，通过轻锥全息QCD获得的波函数可能与雅各布因子的BHL波函数有关。然后，我们通过这两个波函数在轻单夸克模型下计算两光函数的过渡形式〜（TFF）。我们将计算结果与BESIII和其他理论计算的初步实验数据进行了比较。
This work studies the experiments of two-photon processes at BESIII from a theoretical viewpoint in light-cone quantum field theory. We adopt the momentum space wave function of the pion in the light-cone formalism by two forms of the Brodsky-Huang-Lepage~(BHL) prescription and the light-cone holographic QCD. We find that the wave function got by the light-cone holographic QCD can be related to the BHL wave function by a Jacobian factor. Then we calculate the transition form factor~(TFF) of the two-photon process by these two wave functions under the light-cone quark model. We compare the calculated results with the preliminary experimental data at BESIII and also other theoretical calculations.
