Sensitivity studies using multivariate techniques for the search for fully hadronic decays of top squarks with the ATLAS detector — •Nicolas Köhler, Oliver Kortner, and Jonas Graw — Max Planck Institut für Physik, München
The search for the supersymmetric partner of the top quark in final states with jets and missing transverse energy using 36.1 fb−1 of the LHC Run-2 dataset at √s=13 TeV excludes a large range of top squark and LSP (lightest supersymmetric particle) masses with conventional cut-based event selections. In order to further increase the signal sensitivity, different multivariate analysis techniques have been investigated and compared. The achievable gain in sensitivity in the top squark-LSP mass plane with the full Run-2 dataset will be discussed.
