We present results on top quark and on the pairs of top and anti-top quarks, that are expected to be mostly produced through gluon fusion at the LHC. The top mass is determined by making use of a template methods in the single-lepton and all-hadronic channels. The top-quark mass is also extracted fr...

Sumario: | We present results on top quark and on the pairs of top and anti-top quarks, that are expected to be mostly produced through gluon fusion at the LHC. The top mass is determined by making use of a template methods in the single-lepton and all-hadronic channels. The top-quark mass is also extracted from the measurement of the cross-section. We present a measurement of the top quark charge as well as a measurement of the polarization of W bosons in top quark decays to probe the Wtb-vertex. We also present measurements of the spin correlation between top and anti-top quarks as well as of the top-quark charge asymmetry which constitute important tests of QCD and are sensitive to new physics. |
