== Monotop effective theory == === Author === [http://www.cern.ch/fuks Benjamin Fuks] * IPHC Strasbourg / University of Strasbourg * fuks@cern.ch === Description of the model === This model is an extension of the SM, including additional interactions with additional fields so that monotop signatures at colliders are made possible. It follows the model constructed in the paper [http://arxiv.org/abs/1106.6199 arXiv:1106.6199]: J. Andrea, B. Fuks and F. Maltoni, ''Monotops at the LHC.'' === Model files === * [/attachment/wiki/Monotops/monotops.fr monotops.fr]: the main model file. * This model requires the [wiki:StandardModel Standard Model implementation] of !FeynRules. * [/attachment/wiki/Monotops/MonoTops.nb MonoTops.nb]: this is an example Mathematica notebook that loads the model, calculates the Feynman rules and extract the model files within the UFO format. == Matrix element generator files == Several coupling strength are set by hand to zero. We refer to [http://arxiv.org/abs/1106.6199 arXiv:1106.6199] for more informatiom.
