Abstract
Measurements of the inclusive and differential cross section for the production of top quark pairs in proton-(anti)proton collision at center-of-mass energies of 1.96, 7.0 and 8.0 TeV are presented and compared with the latest theory predictions and Monte-Carlo models. In addition, first measurements of the production of top quark pairs in association with additional jets or with a boson are highlighted. All measurements are in good agreement with the Standard Model.
Highlights
The top quark is the heaviest known fundamental particle.Due to its Yukawa coupling being close to unity, it is often believed to play a special role in the electroweak symmetry breaking
It is important to study the top quark in great detail, in order to check the consistency of the Standard Model (SM), and to look for contributions from new physics
ATLAS presented a measurement in the lepton+jets channel, based on a data sample corresponding to L = 5.8 fb 1
Summary
The top quark is the heaviest known fundamental particle. Due to its Yukawa coupling being close to unity, it is often believed to play a special role in the electroweak symmetry breaking. Many models for mt new physics beyond the Standard Model (SM) predict new particles which decay predominantly into top quarks (e.g. Super-Symmetry, SUSY), and new particles may be produced in top decays. Super-Symmetry, SUSY), and new particles may be produced in top decays For these reasons, it is important to study the top quark in great detail, in order to check the consistency of the SM, and to look for contributions from new physics. The production of top quarks in hadron collisions has been studied extensively at the ppcollider Tevatron and D0 experiments) at a center-of-mass energy of [3,4,5,6,7], while the theory status is presented in Refs. Other properties of the top quark and its interactions are discussed in Refs. [3,4,5,6,7], while the theory status is presented in Refs. [8, 9]
