论文摘要
我们研究了彩色玻璃冷凝物有效田间理论中电子蛋白和电子核碰撞中的相干衍射光子和媒介膜产生。我们表明，电子光子和电子矢量膜中的方位角相关相关性对目标的Gluon分布中的非平凡空间相关敏感，并使用空间依赖的McLerran-Venugopalan初始色电荷配置进行了明确的计算，并进行了明确的计算。我们在$ q^2 $和$ | t | $中差异计算横截面，并在电子和电子中找到较大的各向异性 - $ \ mathrm {j}/ψ$ Azimuthal相关性（$ v_ {1,2} \ of Electron-collionics collions collions in Electron-collions in Electron-collions的未来。在电子金碰撞中，发现这些调制明显较小（$ v_ {1,2} <0.1 \％$）。我们还计算出不相干的衍射产生，其中我们发现方位角相关性对目标中的gluon分布的波动敏感。
We study coherent diffractive photon and vector meson production in electron-proton and electron-nucleus collisions within the Color Glass Condensate effective field theory. We show that electron-photon and electron-vector meson azimuthal angle correlations are sensitive to non-trivial spatial correlations in the gluon distribution of the target, and perform explicit calculations using spatially dependent McLerran-Venugopalan initial color charge configurations coupled to the numerical solution of small $x$ JIMWLK evolution equations. We compute the cross-section differentially in $Q^2$ and $|t|$ and find sizeable anisotropies in the electron-photon and electron-$\mathrm{J}/ψ$ azimuthal correlations ($v_{1,2} \approx 2 - 10 \%$) in electron-proton collisions for the kinematics of the future Electron-Ion Collider. In electron-gold collisions these modulations are found to be significantly smaller ($v_{1,2} <0.1 \%$). We also compute incoherent diffractive production where we find that the azimuthal correlations are sensitive to fluctuations of the gluon distribution in the target.
