Top-quark physics: from Run 2 to the HL-LHC

The top quark is a fundamental particle of the standard model and plays an important role in beyond the standard model scenarios. The status of top-quark measurements by ATLAS and CMS is summarized, reporting new recent measurements of top-quark cross sections and top-quark properties. The future high-luminosity run of the Large Hadron Collider is foreseen to produce a huge dataset where top quarks can be studied in detail. The latest projections on expected results on top-quark physics in future high-luminosity runs of the Large Hadron Collider are presented, and the impact of such future measurements on testing the standard model consistency and on constraining new physics scenarios is evaluated.
