论文摘要
Parton饱和度是高能核物理研究边界中最有趣的现象之一，尤其是在即将到来的电子撞机时代（EIC）。深度非弹性散射中的Lepton-Jet相关性为我们提供了通往EIC的Parton饱和的新门户。特别是，我们证明了Lepton-JET相关性的方位角各向异性对EIC运动学区域的饱和动量的强度敏感。与基于共线框架计算的预测相反，当我们比较饱和物理学会导致E + P和E + AU散射时，观察到各向异性的显着核修饰。通过测量EIC的这些谐波系数，可以在不同的碰撞系统中进行定量分析，并提出令人信服的饱和效应证据。
Parton saturation is one of the most intriguing phenomena in the high energy nuclear physics research frontier, especially in the upcoming era of the Electron-Ion Collider (EIC). The lepton-jet correlation in deep inelastic scattering provides us with a new gateway to the parton saturation at the EIC. In particular, we demonstrate that azimuthal angle anisotropies of the lepton-jet correlation are sensitive to the strength of the saturation momentum in the EIC kinematic region. In contrast to the predictions based on the collinear framework calculation, significant nuclear modification of the anisotropies is observed when we compare the saturation physics results in e + p and e + Au scatterings. By measuring these harmonic coefficients at the EIC, one can conduct quantitative analysis in different collisional systems and unveil compelling evidence for saturation effects.
