Description

We present a search for direct bottom squark pair production using the full 2015-2017 ATLAS dataset in final states containing a large number of b-tagged jets and missing transverse energy. Naturalness considerations suggest that the masses of the superpartners of the third-generation quarks should be around the TeV scale and thus would be produced at a considerable rate at LHC. Depending upon the SUSY mass hierarchy considered, the bottom squark may decay through intermediate steps containing Higgs bosons. The results are interpreted in scenarios where the bottom squark decays via the second lightest neutralino and a b-jet and the neutralino subsequently decays to a Higgs boson and the lightest neutralino, whereby the primary decay mode of the Higgs is exploited.
