ATLAS Collaboration, Search for squarks and gluinos using final states with jets and missing transverse momentum with the ATLAS detector in √.. s = 7 TeV

Because of the high number of b quarks in the final state, the factorization method, which provides a background estimate for events with at least three identified b jets, has

The mass distributions observed in data together with the background estimate, its system- atic uncertainty and examples of expected signal are shown in figures 2–4 for the
