Search for direct sbottom and stop pair production in final states with missing transverse momentum and two b-jets with the ATLAS detector

We report on a search for pair production of the scalar partners of bottom and top quarks in 20.1 fb-1 of pp collisions at a centre-of-mass energy of 8 TeV using the ATLAS experiment. The study focuses on final states with large missing transverse momentum, no leptons (electrons or muons) and two jets identified as originating from a b-quark. This final state can be produced in a R-parity conserving minimal supersymmetric scenario, assuming that the scalar bottom decays exclusively into a bottom quark and a neutralino and the scalar top decays into a bottom quark and a chargino, with a small mass difference with the neutralino.
