Search for Supersymmetry in Final States with a Single Lepton, B-jets, and Missing Transverse Energy in Proton-Proton Collisions at √s = 7 TeV

Motivated by supersymmetric models with light top and bottom squarks, a search for supersymmetry in final states with a single lepton, b-jets, and missing transverse energy is performed. The analysis is based on data recorded at the CMS experiment during proton-proton collisions at a center of mass energy of $\sqrt{s}=7$~TeV during 2011, corresponding to an integrated luminosity of 4.96~fb$^{-1}$. Results are interpreted in the context of the constrained Minimal Supersymmetric Standard Model and different heavy flavor simplified models.
