Results are presented of a search for supersymmetric particles in events with large missing transversemomentum and at least one heavy flavour jet candidate in√s = 7 TeV proton–proton collisions. In a datasample corresponding to an integrated luminosity of 35 pb−1 recorded by the ATLAS experiment at theLarge Hadron Collider, no significant excess is observed with respect to the prediction for Standard Modelprocesses. For R-parity conserving models in which sbottoms (stops) are the only squarks to appear inthe gluino decay cascade, gluino masses below 590 GeV (520 GeV) are excluded at the 95% C.L. Theresults are also interpreted in an MSUGRA/CMSSM supersymmetry breaking scenario with tanβ = 40and in an SO(10) model framework.
