Search for Supersymmetry with b-quark Jets and Missing Transverse Energy in pp Collisions at $\sqrt{s}=7$ TeV

We present a search for supersymmetry in events with large $E_{\mathrm{T}}^{\mathrm{miss}}$, no leptons, at least three jets, and one or more $b$-quark jets. We use a data sample corresponding to 4.98 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=7$ TeV collected by the CMS experiment in 2011. The primary sources of standard model background are evaluated using data-driven techniques. We find good agreement between the data and the sum of the background predictions. The results are used to constrain the cross sections for the production of $b$-quark-enriched final states in the context of supersymmetric models.
