Abstract
Recent highlights of measurements by the ATLAS and CMS collaborations involving top quarks produced at the LHC are presented. Emphasis is put on precise inclusive and differential top pair production cross section measurements and comparisons to QCD calculations. Special attention is given to fiducial measurements. Results on electroweak single top quarks production and the recent evidence of top pair produced in associated with vector bosons are summarised. The experimental status of top quark mass measurements is critically reviewed.
Highlights
The large hadron collider LHC at CERN has delivered proton-proton collisions with an integrated l√usm=i7noTseitVy of 5 fb−1 at and 20 fb−1 at a√cse=n8trTe-eoVf-.mTahssis energy of large data set together with the excellent detector performance allowed to make several high precision measurements and to test rare processes.This note reports on the excellent progress made this and last year using the ATLAS [1] and CMS [2] detectors

The advent of LHC has given a large boost to measurements involving top quarks and triggered tremendous activities on the experimental and theoretical side
Summary
The large hadron collider LHC at CERN has delivered proton-proton (pp) collisions with an integrated l√usm=i7noTseitVy of 5 fb−1 at and 20 fb−1 at a√cse=n8trTe-eoVf-.mTahssis energy of large data set together with the excellent detector performance allowed to make several high precision measurements and to test rare processes. This note reports on the excellent progress made this and last year using the ATLAS [1] and CMS [2] detectors. On the experimental side new ideas to reduce experimental uncertainties have been put in action. On the theory side an unprecedented precision has been reached for fixed order calculations and new concepts to build Monte Carlo generators are developed. Detailed tests and searches for particles and interactions beyond the Standard Model coupling to top quarks are reported elsewhere
