In the supersymmetric scenarios considered both of the bottom-squarks decay into a b-quark and the second-lightest neutralino, b~1→b+χ~02 . Each χ~02 is assumed to subsequently decay with 100% branching ratio into a Higgs boson (h) like the one in the Standard Model and the lightest neutralino: χ~02→h+χ~01 . The χ~01 is assumed to be the lightest supersymmetric particle (LSP) and is stable. Two signal mass configurations are targeted: the first has a constant LSP mass of 60 GeV; and the second has a constant mass difference between the χ~02 and χ~01 of 130 GeV. The final states considered contain no charged leptons, three or more b-jets, and large missing transverse momentum. No significant excess of events over the Standard Model background expectation is observed in any of the signal regions considered. Limits at the 95% confidence level are placed in the supersymmetric models considered, and bottom-squarks with mass up to 1.5 TeV are excluded.enHadron-Hadron scattering (experiments)SupersymmetrySearch for bottom-squark pair production with the ATLAS detector in final states containing Higgs bosons, b-jets and missing transverse momentumArtículoAtribution 4.0 International (CC BY 4.0)DOI 10.1007/JHEP12(2019)060
