Search for supersymmetry in events with b-tagged jets and missing transverse momentum in pp collisions at √s = 13 TeV with the ATLAS detector

A search for the supersymmetric partners of the Standard Model bottom and top quarks is presented. The search uses 36.1 fb<sup>-1</sup> of pp collision data at √s = 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. Direct production of pairs of bottom and top squarks...

description A search for the supersymmetric partners of the Standard Model bottom and top quarks is presented. The search uses 36.1 fb<sup>-1</sup> of pp collision data at √s = 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. Direct production of pairs of bottom and top squarks (¯b<sub>1</sub> and ¯t<sub>1</sub>) is searched for in nal states with b-tagged jets and missing transverse momentum. Distinctive selections are de ned with either no charged leptons (electrons or muons) in the nal state, or one charged lepton. The zero-lepton selection targets models in which the ¯b<sub>1</sub> is the lightest squark and decays via ¯b<sub>1</sub>→b¯X<sup>0</sup><sub>1</sub>, where ¯X<sup>0</sup><sub>1</sub> is the lightest neutralino. The one-lepton nal state targets models where bottom or top squarks are produced and can decay into multiple channels, ¯b<sub>1</sub>→b¯X<sup>0</sup><sub>1</sub> and ¯b<sub>1</sub>→ t¯X<sup>±</sup><sub>1</sub>, or ¯t<sub>1</sub> → t¯X<sup>0</sup><sub>1</sub> and ¯t<sub>1</sub> → b¯X<sup>±</sup><sub>1</sub> , where ¯X<sup>±</sup><sub>1</sub> is the lightest chargino and the mass difference m<sub>¯X<sup>±</sup><sub>1</sub></sub> - m<sub>¯X<sup>0</sup><sub>1</sub></sub> is set to 1 GeV. No excess above the expected Standard Model background is observed. Exclusion limits at 95% con dence level on the mass of third-generation squarks are derived in various supersymmetry-inspired simpli ed models.
