本文提出了一个高能碰撞中强子产生的定性模型，该模型考虑了强子产生的两个分量（热分量和硬分量）。包含赝快度分布，d σ/d eta，和横向动量谱，d（2）σ/（d eta dp（T）（2）），由不同的合作被认为是在这个模型。赝快度分布的形状与所介绍的定性图象所能预期的一致。该模型用于为LHC提供预测。数据的质量中心的能量为7 TeV的描述和预测更高的能量等待新的数据。最后，带电粒子的光谱产生的包容性和衍射事件之间的差异进行了讨论，并观察到后者的“热”成分的情况下。(C)2014作者由爱思唯尔公司出版
A qualitative model for hadroproduction in high energy collisions considering two components ("thermal" and "hard") to hadroproduction is proposed. Inclusive psendorapidity distributions, d sigma/d eta, and transverse momentum spectra, d(2)sigma/(d eta dp(T)(2)), measured by different collaborations are considered in terms of this model. The shapes of the pseudorapidity distributions agree with that one can expect from the qualitative picture introduced. The model is used to provide predictions for the LHC. Data up to a centre-of-mass energy of 7 TeV are well described and predictions for higher energies await new data. Finally, the differences between charged particle spectra produced in inclusive and diffractive events are discussed and the absence of the "thermal" component in the latter is observed.
