Title: Search for the direct production of charginos, neutralinos and staus in final states with at least two hadronically decaying taus and missing transverse momentum in $p p$ collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector

Abstract

CERN-LHC. Results of a search for the electroweak associated production of charginos and next-to-lightest neutralinos, pairs of charginos or pairs of tau sleptons are presented. These processes are characterised by final states with at least two hadronically decaying tau leptons, missing transverse momentum and low jet activity. The analysis is based on an integrated luminosity of 20.3 fb-1 of proton-proton collisions at sqrt(s) = 8 TeV recorded with the ATLAS experiment at the Large Hadron Collider. No significant excess is observed with respect to the predictions from Standard Model processes. Limits are set at 95% confidence level on the masses of the lighter chargino and next-to-lightest neutralino for various hypotheses for the lightest neutralino mass in simplified models. In the scenario of direct production of chargino pairs, with each chargino decaying into the lightest neutralino via an intermediate tau slepton, chargino masses up to 345 GeV are excluded for a massless lightest neutralino. For associated production of mass-degenerate charginos and next-to-lightest neutralinos, both decaying into the lightest neutralino via an intermediate tau slepton, masses up to 410 GeV are excluded for a massless lightest neutralino.

Search for direct production of charginos, neutralinos and sleptons in final states with two leptons and missing transverse momentum in $p p$ collisions at $\sqrt{s} =$ 8 TeV with the ATLAS detector

Dataset Aad, Georges ; The ATLAS collaboration

CERN-LHC. Searches for the electroweak production of charginos, neutralinos and sleptons in final states characterized by the presence of two leptons (electrons and muons) and missing transverse momentum are performed using 20.3 fb^-1 of proton-proton collision data at sqrt(s) = 8 TeV recorded in 2012 with the ATLAS experiment at the Large Hadron Collider. No significant excess beyond Standard Model expectations is observed. Limits are set on the masses of the lightest chargino, next-to-lightest neutralino and sleptons for different lightest-neutralino mass hypotheses in simplified models. Results are also interpreted in various scenarios of the phenomenological Minimal Supersymmetric Standard Model.
Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in $\sqrt{s} = 7$ TeV $p p$ collisions with the ATLAS detector

Dataset Aad, Georges ; The ATLAS collaboration

CERN-LHC. Data are presented from the measurements of final states comprising three leptons (electrons or muons) and missing transverse energy in proton proton collisions at a centre-of-mass energy of 7 Tev. The data sample has a total integrated luminosity of 4.7fb-1 and is interpreted in the pMSSM and in simplified models using different signal regions.

Dataset Aad, Georges ; The ATLAS collaboration

CERN-LHC. A search for the direct production of charginos and neutralinos in final states with three leptons and missing transverse momentum is presented. The analysis is based on 20.3 fb^-1 of sqrt(s) = 8 TeV proton--proton collision data delivered by the Large Hadron Collider and recorded in 2012 with the ATLAS detector. Observations are consistent with the Standard Model expectations and limits are set in R-parity-conserving phenomenological Minimal Supersymmetric Standard Models and in simplified supersymmetric models, significantly extending previous results.

Search for supersymmetry in events with large missing transverse momentum, jets, and at least one tau lepton in 20 fb $^{- 1}$ of $\sqrt{s} =$ 8 TeV proton-proton collision data with the ATLAS detector

Dataset Aad, Georges ; The ATLAS collaboration

CERN-LHC. A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using 20.3 fb^-1 of proton-proton collision data at sqrt(s)=8 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectation is observed in the various signal regions and 95% confidence level upper limits on the visible cross section for new phenomena are set. The results of the analysis are interpreted in several SUSY scenarios, significantly extending previous limits obtained inmore »« less

Dataset Aad, Georges ; The ATLAS collaboration

CERN-LHC. The results of a search for pair production of supersymmetric partners of the Standard Model third-generation quarks are reported. This search uses 20.1 fb^-1 of pp collisions at sqrt(s) = 8 TeV collected during the period from March to December 2012 by the ATLAS experiment at the Large Hadron Collider. The lightest bottom and top squarks (b1 and t1 respectively) are searched for in a final state with large missing transverse momentum and two jets identified as originating from b-quarks. No excess of events above the expected level of Standard Model background is found. The results are used tomore »« less
