论文摘要
独家媒介膜的产生是描述质子结构的绝佳探针。在本文中,基于偶极模型,通过Balitsky-Kovchegov(bk)方程的分析解决方案计算出差速器截面,总横截面和纵向横截面与横向横截面的比率。此外,我们还考虑了两个介子波函数模型对结果的影响。我们的预测对介子波函数几乎不敏感,与实验数据一致。 BK方程的分析解决方案可靠地描述了在$ Q^2 $的一定范围内的独家媒介中生产。
Exclusive vector meson production is an excellent probe for describing the structure of proton. In this paper, based on dipole model, the differential cross sections, total cross sections and the ratios of the longitudinal to transverse cross sections of $J/ψ$ and $ρ^0$ productions are calculated with the analytical solution of Balitsky-Kovchegov (BK) equation. In addition, we also consider the influences of two meson wave function models on the results. Our predictions, which are little sensitive to meson wave functions, agree with the experimental data. The analytical solution of BK equation is reliable for description of exclusive vector meson production in a certain range of $Q^2$.
