胶子饱和和Froissart束缚:一种简单的方法

Gluon saturation and the Froissart bound: a simple approach

F. Carvalho, F. O. Duraes, V. P. Goncalves, F. S. Navarra

摘要:

在非常高的能量下,我们期望强子截面满足Froissart束缚,这是强相互作用的一个公认的性质。在这种能量状态下,我们也可以预期彩色玻璃凝聚体的形成,其特征是胶子饱和和一个典型的动量尺度:饱和尺度$Q_s$。本文证明了如果在量子色动力学的非微扰区和微扰区之间存在一个饱和窗口,则总截面满足Froissart界。此外,我们表明,我们的方法使我们能够描述高能量的实验数据的$pp/p\bar{p}$总截面。

英文摘要:

At very high energies we expect that the hadronic cross sections satisfy the Froissart bound, which is a well-established property of the strong interactions. In this energy regime we also expect the formation of the Color Glass Condensate, characterized by gluon saturation and a typical momentum scale: the saturation scale $Q_s$. In this paper we show that if a saturation window exists between the nonperturbative and perturbative regimes of Quantum Chromodynamics (QCD), the total cross sections satisfy the Froissart bound. Furthermore, we show that our approach allows us to describe the high energy experimental data on $pp/p\bar{p}$ total cross sections.
