Mass And Rate Modeling in On-Shell Effective Theories

Marmoset is a strategy and a set of tools for characterizing and fitting physics beyond the Standard Model in a model-independent scheme. We introduce the idea of On-Shell Effective Theories (OSETs), which provide a flexible framework in which to describe new physics in terms of just the masses, production modes, and decay modes of candidate new particles. OSETs are well-suited for Monte Carlo-based analysis and interpretation of new physics at the LHC and TeVatron.

Please look at the following preprints and seminar slides to learn more about Marmoset.

Caveat Emptor! MARMOSET is still (very much) under development, documentation is ongoing, and features may break from time to time. If you are surprised by its behavior or find a bug, please inform the authors and/or report it on the wiki support pages Support.
