- Abstract
- A search for the supersymmetric partners of the Standard Model bottom and top quarks is presented. The search uses 36.1 fb−1 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¯ 1 and t¯ 1) is searched for in final states with b-tagged jets and missing transverse momentum. Distinctive selections are defined with either no charged leptons (electrons or muons) in the final state, or one charged lepton. The zero-lepton selection targets models in which the b¯ 1 is the lightest squark and decays via b¯1→bχ¯10, where χ¯10 is the lightest neutralino. The one-lepton final state targets models where bottom or top squarks are produced and can decay... (More)

The one-lepton final state targets models where bottom or top squarks are produced and can decay into multiple channels, b¯1→bχ¯10 and b¯1→t or t¯1→tχ¯10 and t¯1→b where χ¯1± is the lightest chargino and the mass difference mχ¯1±−mχ¯10 is set to 1 GeV. No excess above the expected Standard Model background is observed. Exclusion limits at 95% confidence level on the mass of third-generation squarks are derived in various supersymmetry-inspired simplified models. © 2017, The Author(s). (Less)
