高能软相互作用的CGC/饱和方法:一个双通道模型

CGC/saturation approach for soft interactions at high energy: a two channel model

E. Gotsman, E. Levin, U. Maor

摘要:

在本文中,我们继续在高能量的强相互作用模型的发展,基于两个成分:CGC/饱和的方法和BFKL Pomeron。在我们的方法中,未知的夸克和胶子禁闭机制,其特征在于从实验数据中提取的几个数值参数。我们证明,双通道模型,成功地描述了实验数据,包括弹性斜率的值和单衍射截面的能量行为。我们表明,我们以前的单通道程函模型[6]与实验数据的不一致源于强子结构的简化方法,而与我们基于CGC/饱和方法的主要理论输入无关。

英文摘要:

In this paper we continue the development of a model for strong interactions at high energy, based on two ingredients: CGC/saturation approach and the BFKL Pomeron. In our approach, the unknown mechanism of confinement of quarks and gluons, is characterized by several numerical parameters, which are extracted from the experimental data. We demonstrate that the two channel model, successfully describes the experimental data, including both the value of the elastic slope and the energy behavior of the single diffraction cross section. We show that the disagreement with experimental data of our previous single channel eikonal model [6] stems from the simplified approach used for the hadron structure, and is not related to our principal theoretical input, based on the CGC/saturation approach.
