After the discovery of the top quark more than 20 years ago, its properties have been studied
in great detail both in production and in decay. Increasingly sophisticated experimental …

A measurement of the charge asymmetry in top-quark pair (tt¯) production in association
with a photon is presented. The measurement is performed in the single-lepton tt¯ decay …

The LHC (Large Hadron Collider) will serve as the energy frontier for high-energy physics
for the next 20 years. The highlight of the LHC running so far has been the discovery of the …

Inclusive and differential measurements of the top-antitop ($ t\bar {t} $) charge asymmetry $
A_\text {C}^{t\bar {t}} $ and the leptonic asymmetry $ A_\text {C}^{\ell\bar {\ell}} $ are …

Recently, experimental collaborations have reported ${\mathcal {O}}(10) $ upper limits on
the signal strength of four-top production at the LHC. Surprisingly, we find that the …

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 …

This book has been written as part of my habilitation at the University of Hamburg. It is
intended to serve graduate students and researchers to get familiar with the stateof-the-art of …

A bstract Measurements of differential cross sections of top quark pair production in
association with jets by the ATLAS experiment at the LHC are presented. The …

The t t-bar charge asymmetry is measured in proton-proton collisions at a centre-of-mass
energy of 8 TeV. The data, collected with the CMS experiment at the LHC, correspond to an …
