The impact of the partonic structure on the description of the hadronic cross-sections is investigated considering a multichannel eikonal model based on the Good–Walker approach. The total, elastic and single diffractive cross-sections are estimated considering different parametrizations for the parton distribution functions and the predictions are compared with the experimental data for proton–proton [Formula: see text] and antiproton–proton [Formula: see text] collisions. We show that the description of the high-energy behavior of the hadronic cross-sections is sensitive to the partonic structure.

研究分子结构对高能强子碰撞描述的影响

考虑基于 Good-Walker 方法的多通道 eikonal 模型，研究了部分结构对强子截面描述的影响。考虑到部分子分布函数的不同参数化估计总的、弹性的和单衍射的横截面，并将预测与质子-质子[公式：见文本]和反质子-质子[公式：见文本]碰撞的实验数据进行比较. 我们表明，强子截面的高能行为的描述对分子结构很敏感。
