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: (i) Extractions of the strong coupling constant $\alpha_s(m_{Z}$; (ii) Comparison of data to fixed-order (N$^{n}$LO) perturbative QCD calculations; (iii) Determinations of parton distribution functions (PDFs); (iv) Comparison of data to resummed (N$^{n}$LL) pQCD calculations; (v) Parton showering and jet substructure analyses; (vi) Semi-hard (double parton interactions, multiparton interactions, hard diffraction), and soft (elastic and diffractive) QCD scatterings; and (vii) Studies of parton hadronization in $e^+e^-$ and p-p collisions.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating very compact bibliographies which can be beneficial to authors and readers, and in "proceeding" format which is more detailed and complete.
