Search for supersymmetry using events with three leptons, multiple jets, and missing transverse momentum in 13.0 fb$^{-1}$ of pp collisions with the ATLAS detector at $\sqrt{s}=8$ TeV

We report on a search for supersymmetry using events with three leptons, four or more jets, and missing transverse momentum. The search utilizes 13.0 fb$^{-1}$ of proton-proton collision data collected at $\sqrt{s}=8$ TeV with the ATLAS detector at the Large Hadron Collider. The data are found to be...

description We report on a search for supersymmetry using events with three leptons, four or more jets, and missing transverse momentum. The search utilizes 13.0 fb$^{-1}$ of proton-proton collision data collected at $\sqrt{s}=8$ TeV with the ATLAS detector at the Large Hadron Collider. The data are found to be in agreement with the Standard Model expectation. The result is interpreted in terms of two simplified supersymmetry models. For pair-production of gluinos that decay into top quarks and neutralino via off-shell top squarks ($pp\to\tilde{g} \tilde{g}$, $\tilde{g}\to\tilde{t}_1^*\bar{t}$, and $\tilde{t}_1^*\to\tilde{\chi}^0_1t$), gluinos with masses lower than 860 GeV are excluded at 95% CL for a light neutralino. For pair-production of bottom squarks each decaying via $\tilde{b}\to t+\tilde{\chi}^{\pm}_1$ (where $\tilde{\chi}^{\pm}_1\to W^\pm\tilde{\chi}^0_{1}$) bottom squarks masses up to 430 GeV are excluded, depending on the assumptions on neutralino and chargino masses.
