“…This allows for the correct treatment of their correlations and the evaluation of the combined uncertainty. These results complement the CMS dilepton and kinematics-based lepton þ jets analyses which are described elsewhere [9,10]. The ATLAS experiment has also measured the t " t cross section in the dilepton and lepton þ jets channels at 7 TeV [11].…”

RG-improved single-particle inclusive cross sections and forward-backward asymmetry in $ t\bar{t} $ production at hadron colliders

“…The blue band shows the dependence of a D0 measurement of the total cross section on m t [81]. Right: The same for the LHC but with a comparison to recent CMS [11] and ATLAS [12] measurements.…”

“…In the last 15 years a few thousand top-quark pair events were studied by the CDF and D0 collaborations. The LHC is now running at a center-of-mass energy of 7 TeV, and very recently the first measurements of the total pair-production cross section was performed by the CMS [11] and ATLAS [12] collaborations. Hopes are that it will be possible to obtain an integrated luminosity of up to 1 fb −1 , which would produce roughly 150,000 tt events before selection [13].…”

Search for Supersymmetry at the LHC in Events with Jets and Missing Transverse Energy

“…The event selection, following closely the prescription described in Ref. [42], requires a single, isolated muon with p T > 10 GeV in the final state and the transverse mass of the muon and H T system to be larger than 30 GeV to ensure a sample rich in W bosons. The muon is required to be separated from the closest jet in the event by Á and Á such that the distance ÁR ffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi ffi Á 2 þ Á 2 p > 0:5.…”
