Search for supersymmetry in pp collisions at sqrt(s) = 8 TeV in events with three leptons and at least one b-tagged jet

Results are reported from a search for new physics processes in events with three leptons and at least one b-tagged jet. The analysis is based on a sample of proton-proton collisions at a center-of-mass energy of 8 TeV with an integrated luminosity of 19.5/fb, collected by the CMS detector at the LHC. The event selection focuses on signatures for supersymmetry (SUSY) that include multiple W or Z bosons and b-jets in the final state, and the b-jet multiplicity is used to define low-background search regions. The standard model background contributions are determined using well-established techniques that are based on control samples in the data. The observed yields in the data are consistent with the background predictions, and the results are used to obtain upper limits on the production cross sections for several SUSY event topologies defined in the framework of simplified models.
