Zero momentum gluons and the total pp and pbarp cross-sections

A. Achilli, R. M. Godbole, A. Grau, G. Pancheri, Y. N. Srivastava

摘要:

我们描述了一个基于QCD的总截面模型,该模型采用程函表象并引入QCD微喷流来驱动截面能量的上升,而碰撞参量分布则通过对部分子-部分子相互作用中产生微喷流的软胶子的横向动量分布进行傅立叶变换来获得.一个奇异的,但在红外区域的运行耦合常数积分表达式是这个模型的一部分。

英文摘要:

We describe a QCD motivated model for total cross-sections which uses the eikonal representation and incorporates QCD mini-jets to drive the rise with energy of the cross-section, while the impact parameter distribution is obtained through the Fourier transform of the transverse momentum distribution of soft gluons emitted in the parton-parton interactions giving rise to mini-jets in the final state. A singular but integral expression for the running coupling constant in the infrared region is part of this model.
