Abstract

The exclusive photo- and electroproduction of light vector mesons like $ρ, ω,$ and $ϕ$ is studied in $γ p$ collisions within the color dipole formalism with vector meson wave functions obtained using the AdS/QCD holographic approach. This setup provides a good description of the existing data for the ground vector mesons $ρ (1 S), ω (1 S), and ϕ (1 S)$ and permits us to make predictions for the corresponding excited states. The results show significant theoretical uncertainties related to modeling the partial dipole amplitude, which can be constrained with upcoming measurements in future hadron colliders.

利用全息波函数模型独家生产地面和激发光矢量介子

在彩色偶极子形式主义下的γp$$ \gamma p$$碰撞中，利用AdS/QCD全息方法获得的矢量介子波函数，研究了ρ,ω,$$ \rho,\omega,$$和j$$ \phi$$等轻矢量介子的排他性光生和电生。这种设置很好地描述了地面矢量介子ρ(1S),ω(1S),和j(1S)$$ \rho (1S),\kern0.3em \omega (1S),\kern0.3em \mathrm{and}\kern0.3em \phi (1S) $$的现有数据，并允许我们对相应的激发态进行预测。结果显示了与部分偶极子振幅建模相关的重大理论不确定性，这些不确定性可以通过未来强子对撞机的测量来加以约束。

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
