Using e.g. official as your database path will currently not work (sorry!). Please use instead full database path names, e.g. for the official 1.2.2 database. We apologize for the inconvenience.

28 Nov 2018: SModelS version 1.2.2 is now available (what’s new)

If you use SModelS, please cite the following papers:


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. The main SModelS ingredients are

SMS wishlist

A wishlist regarding the presentation of SMS results was worked out at the 2013 Les Houches workshop, see this page.
