Search for top squarks in events with a Higgs or Z boson using 139 fb−1 of pp collision data at √s=13 TeV with the ATLAS detector
Original language description
This paper presents a search for direct top squark pair production in events with missing transverse momentum plus either a pair of jets consistent with Standard Model Higgs boson decay into b-quarks or a same-flavour opposite-sign dilepton pair with an invariant mass consistent with a Z boson. The analysis is performed using the proton–proton collision data at s=13sqrt{s}=13s =13 TeV collected with the ATLAS detector during the LHC Run-2, corresponding to an integrated luminosity of 139 fb−1^{-1}−1. No excess is observed in the data above the Standard Model predictions. The results are interpreted in simplified models featuring direct production of pairs of either the lighter top squark (t~1 ilde{t}_1t~1) or the heavier top squark (t~2 ilde{t}_2t~2), excluding at 95% confidence level t~1 ilde{t}_1t~1 and t~2 ilde{t}_2t~2 masses up to about 1220 and 875 GeV, respectively.n
