Experimental QCD summary (ICHEP 2020)

This writeup summarizes the main experimental studies of the strong interaction, theoretically described by quantum chromodynamics (QCD), that were presented during the ICHEP-2020 conference. The latest results, measured mostly in p-p collisions at the LHC, are categorized in seven broad topics: \begin{enumerate} \item Extractions of the strong coupling constant $\alpha_s(m_{\rm Z})$; \item Comparison of data to fixed-order (N$^{\rm n}$LO) perturbative QCD calculations; \item Determinations of parton distribution functions (PDFs); \item Comparison of data to resummed (N$^{\rm n}$LL) pQCD calculations; \item Parton showering and jet substructure analyses; \item Semi-hard (double parton interactions, multiparton interactions, hard diffraction), and soft (elastic and diffractive) QCD scatterings; \item Studies of parton hadronization in $e^+e^-$ and p-p collisions. \end{enumerate} Published in: PoS ICHEP2020 (2021) 012 (DOI:10.22323/1.390.0012)
