In this brief note, we confront our results on diffractive photoproduction of mesons with the putative gluon shadowing ratio defined as , where is the result in impulse approximation. Building on our earlier description of the process in the color-dipole approach, where we took into account the rescattering of states only, we demonstrate that the inclusion of -Fock states improves the description at small commonly associated with gluon shadowing.

核中的胶子阴影以及[公式省略]状态在核-核碰撞中 J/ψ 相干光产生中的作用


在这篇简短的说明中，我们面对介子的衍射光产生的结果，假定的胶子阴影比定义为 ，其中 是脉冲近似的结果。基于我们之前对颜色偶极子方法过程的描述，我们仅考虑了状态的重新散射，我们证明了 -Fock 状态的包含改善了通常与胶子阴影相关的小描述。
