Search for supersymmetry in pp collisions at sqrt(s) = 7TeV in final states with missing transverse momentum, b-jets and no leptons with the ATLAS detector

A search for supersymmetric particles in events with large missing transverse momentum, heavy flavour jet candidates and no leptons (e, mu) in sqrt(s) = 7TeV proton-proton collisions is presented. In a data sample corresponding to an integrated luminosity of 833\pb recorded by the ATLAS experiment at the Large Hadron Collider, no significant excess is observed with respect to the prediction for Standard Model processes. For R-parity conserving models in which sbottoms are the only squarks to appear in the gluino decay cascade, gluino masses below 720~GeV are excluded at the 95\% C.L. Model-independent cross section upper limits are provided in the context of simplified models and the result is also interpreted in the context of grand unification SO(10) models.
