Standard Model soft and hard QCD at ATLAS and CMS

The events collected at the LHC are dominated by production of hard and soft QCD processes. The large dataset collected during Run 2 allows for multidifferential measurements of large momentum QCD events, that are versatile tools to investigate fundamental aspects such as the strong constant, PDFs, and parton shower modelling. Special runs of the LHC allow instead to check the effect of soft QCD in events with proton diffraction or scattering. The contribution presented here shows highlights from both the ATLAS and CMS collaborations at the LHC.
