A search for supersymmetry in events with one or two soft leptons and large missing transverse momentum is presented, based on 19.7 fb^-1 of 8 TeV pp collisions recorded with the CMS detector. This final state is typical for SUSY scenarios with a small mass splitting between the LSP and the top squark or chargino (compressed mass spectra). A hard Initial State Radiation jet is used to trigger such events. The event selection and the methods for estimating the Standard Model background are presented. The data are found to be in agreement with the predicted yields from Standard Model processes, and as a result exclusion limits are set for different compressed signal scenarios.
