高能质子碰撞的大横动量喷注产生

山东大学学报(自然科学版) 1984年第4期 34-39页

作者：侯云智山东大学物理系

本文研讨了目前流行的几种部分子结构函数及其适用范围。根据QCD微扰论计算了Pr≥2Gev/C的各种部分子喷注的总截面随能量的变化。考虑到结构函数的标度破坏,但喷注的质量效应和部分子的内禀横动量分布对总截面影响并不显著。本文的结果... 详细信息

本文研讨了目前流行的几种部分子结构函数及其适用范围。根据QCD微扰论计算了Pr≥2Gev/C的各种部分子喷注的总截面随能量的变化。考虑到结构函数的标度破坏,但喷注的质量效应和部分子的内禀横动量分布对总截面影响并不显著。本文的结果为蒙特卡洛法研究宇宙线的双集团事例率,克服原朴素部分子模型预言的比实验偏低的困难提供理论依据。同时,为在超高能区验证微扰QCD的适用性提供重要信息。
