Relative pair cross sections σp(EγZ) have been measured for energies 1.120, 1.172, 1.333, 1.560, 2.225, and 2.754 MeV and Z = 22, 29, 42, 48, 74, and 82. Results obtained through intensity analysis of annihilation spectra have been normalized to σ(2.754, 82) = 3.30 b/atom.

The latest top quark studies in proton-proton collisions at a centre-of-mass energy of 7 and 8 TeV with the ATLAS detector are reported. We present recent results on the top pair production inclusive cross-sections, top pair production differential cross-section in the resolved and boosted regimes, single top-quark production cross-sections measured in the t-channel, s-channel and W-boson associated processes, as well as the determination of the CKM matrix element [Formula: see text]. The results are compared with theoretical expectations. Latest ATLAS results on top properties will be also shown in terms of direct and pole mass, spin correlations and charge asymmetry.
