论文摘要
在这项工作中，我们考虑了QCD Parton饱和模型，以描述高能量极限的软相互作用。对于质子 - 蛋白质和脓性 - 普罗替型碰撞，获得了总和和弹性斜率参数，并将其与最近的实验结果进行了比较。这些分析是在颜色偶极式形式主义中进行的，考虑到已针对DIS数据进行了测试的饱和模型。要点是，软相互作用之间的匹配发生在饱和区域中，可以通过高密度QCD方法来描述。讨论是在与计算相关的主要理论不确定性上进行的。
In this work we consider the QCD parton saturation models to describe soft interactions at the high energy limit. The total and elastic cross sections as well as the elastic slope parameter are obtained for proton-proton and pion-proton collisions and compared to recent experimental results. The analyses are done within the color dipole formalism taking into account saturation models which have been tested against DIS data. The main point is that the match between soft and hard interaction occurs in the saturation region which can be described by high density QCD approaches. Discussion is performed on the main theoretical uncertainties associated with calculations.
