论文摘要
在本文中，我们研究了光$ρ$，$ω$和$ ϕ $梅森的全部和差异观测值，作为$γp$ collision collision and Momentum Transfer squal的质量中心能量的功能。相应的介体波函数已经在相对论ADS/QCD全息方法的框架中计算出来。在彩色偶极子图片中实现了对地面$ρ（1s）$，$ω（1s）$和$ ϕ（1s）$和$ ϕ（1s）$和$ ϕ（1s）$的所有可用数据的令人满意的描述。最后，激发$ρ（2s）$，$ω（2s）$和$ ϕ（2s）$状态生产的关键可观察物在$γ^{（*）} p $ collisiation中使用了常见的波函数形式主义。这项研究揭示了来自非扰动运动率域中部分偶极振幅的建模产生的较大理论不确定性。因此，后者可以通过对激发态的光生量的未来测量受益。
In this paper, we study total and differential observables of electro- and photoproduction of light $ρ$, $ω$ and $ϕ$ mesons as functions of the center-of-mass energy of the $γp$ collision and momentum transfer squared $|t|$. The corresponding vector mesons wave functions have been computed in the framework of relativistic AdS/QCD holographic approach. A satisfactory description of all available data on ground-state $ρ(1S)$, $ω(1S)$ and $ϕ(1S)$ mesons production cross sections has been achieved in the color dipole picture. Finally, the key observables of excited $ρ(2S)$, $ω(2S)$ and $ϕ(2S)$ states production in $γ^{(*)} p$ collisions have been presented here using a common wave function formalism. This study reveals a large theoretical uncertainty coming from the modeling of the partial dipole amplitude in the nonperturbative kinematical domain. Hence, the latter could benefit from future measurements of photoproduction of the excited states.
