The analyzed dataset is based on proton-proton collisions at √s = 13 TeV delivered by the Large Hadron Collider and recorded by the ATLAS detector from 2015 to 2018, and corresponds to an integrated luminosity of 139 fb-1. The observed data are compatible with the expected Standard Model background. Results are interpreted in a simplified model where each bottom squark is assumed to decay into the second-lightest neutralino χ 20 and a bottom quark, with χ 20 decaying into a Higgs boson and the lightest neutralino χ 10. The search focuses on final states where at least one Higgs boson decays into a pair of hadronically decaying ꞇ-leptons. This allows the acceptance and thus the sensitivity to be significantly improved relative to the previous results at low masses of the χ 20, where bottom-squark masses up to 850 GeV are excluded at the 95% confidence level, assuming a mass difference of 130 GeV between χ 20 and χ 10. Model-independent upper limits are also set on the cross section of processes beyond the Standard ModelAmerican Physical SocietyDepartamento de Física TeóricaFacultad de Ciencias20212021-08-31research articlehttp://purl.org/coar/resource_type/c_2df8fbb1VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10486/705508https://dx.doi.org/10.1103/PhysRevD.104.032014reponame:Biblos-e Archivo.
