论文摘要
提出了用于高能$ pp $碰撞中单个和双衍射激发的描述的现象学模型。考虑到良好的沃克方法，我们为散射算子的本征态以及对它们之间的相互作用进行处理，并通过扰动QCD驱动的横截面的高能量行为。分析了总，弹性，单一和双衍射横截面的行为，并对LHC运行3的能量进行预测，并得出了宇宙射线实验的行为。我们证明该模型描述了横截面的能量依赖性的当前数据。还提供了与$ρ$参数的最新数据和差异弹性横截面的比较，并讨论了当前模型的缺点。
A phenomenological model for the description of the single and double diffractive excitation in $pp$ collisions at high energies is presented. Considering the Good -- Walker approach, we propose a model for the eigenstates of the scattering operator and for the treatment of the interaction between them, with the high energy behavior of the cross section driven by perturbative QCD. The behavior of the total, elastic, single and double diffractive cross sections are analyzed and predictions for the energies of Run 3 of the LHC and those of the Cosmic Rays experiments are derived. We demonstrate that the model describes the current data for the energy dependence of the cross sections. A comparison with the recent data for the $ρ$ parameter and the differential elastic cross section are also presented and shortcomings of the current model are discussed.
