For convenience a .bib file is provided with the code containing all relevant references.
Likewise, a .bib file is provided in the database folder with references to all the ATLAS and CMS analyses used.
SModelS is based on a general procedure to decompose Beyond the Standard Model (BSM) collider signatures presenting a Z2 symmetry into Simplified Model Spectrum (SMS) topologies. Our method provides a way to cast BSM predictions for the LHC in a model independent framework, which can be directly confronted with the relevant experimental constraints. Our concrete implementation currently focusses on supersymmetry searches with missing energy, for which a large variety of SMS results from ATLAS and CMS are available. The main ingredients are
- the decomposition of the BSM spectrum into SMS topologies
- a database of experimental SMS results
the interface between decomposition and results database (to check limits)
