Combination of ATLAS and CMS top-quark pair cross section measurements using proton-proton collisions at sqrt(s) = 7 TeV /CMS Collaboration
% A combination of top-quark pair production cross-section ($\sigma_{\rm t\bar t}$) measurements at a centre-of-mass energy of 7~TeV performed by the ATLAS and CMS experiments at the LHC is presented. The combination includes $\sigma_{\rm t\bar t}$ measurements in the lepton+jets, di-lepton, and all jets channels which use between 0.7 and 1.1~fb$^{-1}$ of proton-proton collisions. The combined preliminary LHC measurement of the top-quark pair production cross-section is $\sigma_{\rm t\bar t} = 173.3 \pm 2.3~\mathrm{(stat.)} \pm 7.6~\mathrm{(syst.)} \pm 6.3~\mathrm{(lumi.)}~\mathrm{pb} = 173.3 \pm 10.1~\mathrm{pb}$ for a top-quark mass of $172.5\mathrm{\ GeV}/c^2$, corresponding to a total uncertainty of 5.8\%. The result is in agreement with the standard model prediction..

Search for Single Top tW Associated Production in the Dilepton Channel at CMS / Ott, Jochen (Karlsruhe U., EKP) /CMS Collaboration
We present a first study of the single top quark W-associated production (tW) in proton-proton collisions at the LHC at a centre-of-mass energy of 7TeV, using data collected with the CMS experiment. The search is performed in the dileptonic final states ee/e$\mu$/$\mu\mu$ with a selection based on kinematical properties and b-tagging information. The contribution of the Z+jets processes to the background is estimated from a sideband in data. Two $\rm t\bar t$ dominated control regions are used to constrain the normalization of top quark pair production in the signal region. [...]

QCD and Top physics studies in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector / Barisonzi, M (Wuppertal U.)
Beginning from 2010, ATLAS collected proton-proton collision data at a centre-of-mass energy of 7~TeV, accumulating by the Spring of 2011 an integrated luminosity of ~200 inverse picobarn. [...]

Search for $t\bar tH/A \rightarrow t\bar tt\bar t$ production in the multilepton final state in proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector
A search for a new heavy scalar or pseudo-scalar Higgs boson ($H/A$) produced in association with a pair of top quarks, with the Higgs boson decaying into a pair of top quarks ($H/A \rightarrow t\bar t$) is reported. [...]

Associated $Z$ bozon production in the forward region / Lionetto, F (Zurich U.)
The $Z$ plus $\mathrm{jet}$ and $Z$ plus $D$ production cross-sections in proton-proton collisions at a centre-of-mass energy $\sqrt{s} = 7$~TeV and the inclusive $Z$ boson production cross-section in proton-lead collisions at a centre-of-mass energy per proton-nucleon pair $\sqrt{s_{NN}} = 5$~TeV are measured by LHCb. These results are briefly presented here..

Measurement of inclusive isolated prompt photons in pp collisions with the ATLAS detector. / Polci, F (LPSC Grenoble)
A measurement of the cross section for the inclusive production of isolated prompt photons in pp collisions at a centre-of-mass energy sqrt(s) = 7TeV is presented. Photon candidates are identified by combining information from the calorimeters and from the inner tracker. [...]
