Abstract

CERN-LHC. Results from a search for supersymmetry in events with four or more leptons including electrons, muons and taus are presented. The analysis uses a data sample corresponding to 20.3 fb^{-1} of proton-proton collisions delivered by the Large Hadron Collider at sqrt(s) = 8 TeV and recorded by the ATLAS detector. Signal regions are designed to target supersymmetric scenarios that can be either enriched in or depleted of events involving the production of a Z boson. No significant deviations are observed in data from Standard Model predictions and results are used to set upper limits on the event yields from processes beyond the Standard Model. Exclusion limits at the 95% confidence level on the masses of relevant supersymmetric particles are obtained. In R-parity-violating simplified models with decays of the lightest supersymmetric particle to electrons and muons, limits of 1350 GeV and 750 GeV are placed on gluino and chargino masses, respectively. In R-parity-conserving simplified models with heavy neutralinos decaying to a massless lightest supersymmetric particle, heavy neutralino masses up to 620 GeV are excluded. Limits are also placed on other supersymmetric scenarios.

Search for supersymmetry in events with four or more leptons in $\sqrt{s} = 13$ TeV $p p$ collisions with ATLAS

Results from a search for supersymmetry in events with four or more charged leptons (electrons, muons and taus) are presented.
Search for supersymmetry in events with four or more leptons and missing transverse momentum in pp collisions at $\sqrt{s} = 7$ TeV with the ATLAS detector

Dataset Aad, Georges

CERN-LHC. Study of events with four or more leptons (electrons or muons) and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data were collected in 2011 and have an integrated total luminosity of 2.06 fb-1. Note that the additional requirements of missing ET > 50 GeV and a veto on the Z0 mass region, used in the analysis, is not applied in these tables, due to lack of statistics at those stages.
Search for R-parity-violating supersymmetry in events with four or more leptons in $\sqrt{s} = 7$ TeV $p p$ collisions with the ATLAS detector

Dataset Aad, Georges

CERN-LHC. Measurement of final states with four or more leptons (electrons or muons) produced in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data sample has a total integrated luminosity of 4.7 fb-1. Comparisons with the Standard Model are made in two signal regions: one that requires moderate values of missing transverse momentum and the other that requires large effective mass. The data are interpreted in a simplified model of R-parity-vilaiting supersymmetry and in an R-partiy-violating MSUGRA/CMSSM model.

Search for new particles in events with one lepton and missing transverse momentum in $p p$ collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector

Dataset Aad, Georges

CERN-LHC. This paper presents a search for new particles in events with one lepton (electron or muon) and missing transverse momentum using 20.3 fb-1 of proton-proton collision data at sqrt(s)=8 TeV recorded by the ATLAS experiment at the Large Hadron Collider. No significant excess beyond Standard Model expectations is observed. A WPRIME with Sequential Standard Model couplings is excluded at the 95% confidence level for masses up to 3.24 TeV. Excited chiral bosons (W*) with equivalent coupling strengths are excluded for masses up to 3.21 TeV. In the framework of an effective field theory limits are also set on themore »« less
