Sumario:A search for anomalous production in the same-sign dilepton final state with at least two b-jets and missing energy is performed. This analysis uses a data sample collected with the CMS detector of proton-proton collisions at a centre-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 4.7~fb$^{-1}$. No excess above the standard model background expectation is observed. Upper limits at 95\% confidence level are set on the number of events from non-standard model sources. These limits are used to set constraints on a number of new physics models. Information on acceptance and efficiencies are also provided so that the results can be used to confront additional models in an approximate way.
