Top-quark physics at the Large Hadron Collider

This experimental review gives an overview of top-quark measurements performed by the two general-purpose detectors ATLAS and CMS during the first few years of running of the Large Hadron Collider. In the years 2010-2012 each experiment collected 5 fb(-1) of pp collision data at root s = 7 TeV and 20 fb(-1) at root s = 8 TeV, allowing detailed studies of topquark production and decays, and measurements of the properties of the top quark with unprecedented precision.
