摘要
用Ｃｈｏｕ－Ｙａｎｇ模型构造了一个用于＝２６ＧｅＶ到２２ＴｅＶ的软强子非单衍相互作用ＭｏｎｔｅＣａｒｌｏ产生器．结合大横动量喷注产生过程的ｐＱＣＤ计算和相应的部分子强子化方案，较好地再现了高能区实验的结果．平滑地外推到超高能区，预言了非弹性度随能量下降的趋势．
A Monte carlo generator of Chou-Yang model to describe proton-proton soft scattering is developed based on pp NSD scattering data and the subtraction of the contribution due to hard scattering.This generator can be used for the description of soft hadronic NSD proton-proton interactions from 26 GeV to 22 TeV.Major experimental results observed on colliders are reproduced reasonably by using the generator combined with the calculation of large pr jet production and hadronization.A decrease of inelasticity with the increase of energy is predicted.
