论文摘要
我们在彩色玻璃冷凝水框架中的超高碰撞中，在中高率中提供了两丝产生的第一个计算。为了估计与几乎真实光子波功能的不良理解相关的系统不确定性，我们考虑了两个截然不同的模型：稀释夸克 - 易夸克偶极子近似值和一个载体梅森，其中麦克雷伦 - venugopalan模型近似颜色电荷密度。在实验相关的范围内，靶核可以通过高度饱和的状态忠实地近似。这一简化使我们能够执行有效的数值模拟，并提取两种胶结相关函数和相关的方位角谐波。
We provide the first calculation of two-gluon production at mid-rapidity in ultra-peripheral collisions in the Color Glass Condensate framework. To estimate systematic uncertainty associated with poor understanding of the wave function of the nearly real photon, we consider two diametrically different models: the dilute quark-antiquark dipole approximation and a vector meson, in which color charge density is approximated by McLerran-Venugopalan model. In the experimentally relevant range, the target nucleus can be faithfully approximated by a highly saturated state. This simplification enables us to perform efficient numerical simulations and extract the two-gluon correlation functions and the associated azimuthal harmonics.
