Resumen:
The results of a search for pair production of the
scalar partners of bottom quarks in 2.05 fb^-1 of pp collisions at
sqrt{s} = 7 TeV using the ATLAS experiment are reported. Scalar bottoms
are searched for in events with large missing transverse momentum and
two jets in the final state, where both jets are identified as
originating from a b-quark. In an R-parity conserving minimal
supersymmetric scenario, assuming that the scalar bottom decays
exclusively into a bottom quark and a neutralino, 95% confidence-level
upper limits are obtained in the tilde{b}_1 - tilde{chi}^0_1 mass plane
such that for neutralino masses below 60 GeV scalar bottom masses up to
390 GeV are excluded.
