Measurement of the forward-backward asymmetry of electron and muon pair-production in p p collisions at s = 7 TeV with the ATLAS detector

The Observable is calculated as a function of the di-lepton invariant mass. The forward backward asymmetry has been calculated at detector level and then corrected with an unfolding technique. Two corrections are applied: detector resolution and QED radiative corrections (namely mass bin migration), dilution. The results are presented for the cases when only the mass bin migration correction has been applied and when both the mass bin migration and dilution corrections have been applied.

Study of ordered hadron chains with the ATLAS detector

Study of 2-particle correlations in the context of coherent particle emission, test of the model of quantized fragmentation of a helical QCD string. Low intensity minimum bias pp data collected at centre-of-mass energy of 7 TeV. Acceptance region pT>100 MeV and |eta|<2.5. Non-identified particles, treated as pions.

Search for supersymmetry in final states with two same-sign or three leptons and jets using 36 fb &#x2212; 1 of s = 13 TeV p p collision data with the ATLAS detector

CERN-LHC. A search for strongly produced supersymmetric particles using signatures involving multiple energetic jets and either two isolated same-sign leptons (electrons or muons), or at least three isolated leptons, is presented. The analysis relies on b-tagged jets and missing transverse momentum, to achieve good sensitivity.
