t-tbar Pair production cross section measurement at the LHC    [PDF]

Tae Jeong Kim

Measurement of $t\bar{t}$ pair production cross sections with an integrated
luminosity of around 1 fb$^{-1}$ at $\sqrt{s}$ = 7 TeV obtained with the ATLAS
and CMS detectors are reported. The inclusive cross sections in dilepton (ee,
$e\mu$, $\mu\mu$ and $\mu\tau$), lepton+jets (e, $\mu$) and all hadronic decay
modes are measured. In addition to inclusive cross section measurement, the
study of jet multiplicity with additional jets are also presented, which is
important to constrain the initial state radiation. Measurement of the charge
asymmetry at the LHC is also presented. All measurements are compatible with
Standard Model predictions.
