论文摘要
在这项贡献中，我们介绍了关于准真实光子 - 普罗顿相互作用中有关双Parton散射（DPS）的研究的主要结果。我们显示了在HERA观察到的四射流照相制作的DPS横截面的首次评估。为此，首次计算出$γ-P $有效横截面。该分析的主要结果之一是DPS贡献不可忽略，并且可能可测量。此外，可能的未来数据可用于获取有关在其他过程中无法访问的横向质子结构的新信息。
In this contribution we present the main results of the investigation about double parton scattering (DPS) in quasi-real photon-proton interactions. We show the first evaluation of the DPS cross-section at leading-order for the four-jet photo-production observed at HERA. To this aim the $γ-p$ effective cross section has been computed for the first time. One of the main outcomes of this analysis is that the DPS contribution is not negligible and potentially measurable. Furthermore, possible future data could be used to get new information on the transverse proton structure not accessible in other processes.
