masses of the particles involved, providing a wider spectrum of mass spectra than allowed by the CMSSM. A minimum requirement of ${\cal
  O}(100~\GeV)$ on the mass difference between the mother particle and the LSP is applied, to remove phase space where the jets from superpartner decays become soft and the signal is detected only when it is given a boost by associated jet production. By restricting attention to SMS scenarios with large mass differences, we avoid the region of phase space where accurate modeling of initial- and final-state radiation from quarks and gluons is required, and where the description of the signal shape has large uncertainties.

The production of the primary particles in each SMS is modeled with SUSY processes in the appropriate decoupling limit of the other superpartners. In particular, for $\sQua\,\sQua^*$ production, the gluino mass is set to a very large value so that it has a minimal effect on the kinematics of the squarks. The mass spectrum and decay modes of the particles in a specific SMS point are fixed using the SLHA input files, which are processed with v6.426 with Tune Z2 [@Field:2010bc; @UEPAS] to produce signal events as an input to a parameterized fast simulation
