Sergey Ostapchenko

AI总结:

本文介绍QGSJET-III高能强子碰撞模型的物理形式体系,重点阐述高阶扭曲修正与颜色涨落效应的实现,并展示其对质子-质子总、弹性及衍射截面能量依赖的模拟结果。

摘要:

本文描述了QGSJET-III高能强子碰撞蒙特卡洛发生器所包含的物理内容。特别地,较为详细地讨论了硬部分子散射过程中高阶扭曲修正的唯象实现方法。此外,还讨论了所谓的“颜色涨落”效应的处理方法,该效应与将强子波函数分解为若干Fock态有关,这些Fock态具有不同的空间尺度和不同的部分子密度。文中给出了关于质子-质子总截面、弹性截面和衍射截面能量依赖性的若干模型结果。

英文摘要:

The physics content of the QGSJET-III Monte Carlo generator of high energy hadronic collisions is described. In particular, a phenomenological implementation of higher twist corrections to hard parton scattering processes is discussed in some detail. Additionally addressed is the treatment of the so-called ``color fluctuation'' effects related to a decomposition of hadron wave functions into a number of Fock states characterized by different spatial sizes and different parton densities. Selected model results regarding the energy-dependence of the total, elastic, and diffractive proton-proton cross sections are presented.
