=== Description of the model & reference ===

The top effective theory model contains all the dimension-six operators affecting top pair production, single top pair production and top decay by interfering with the SM amplitudes.

Here is the model file of the TopEffTh model [/attachment/wiki/TopEffTh/TopEffTh.fr TopEffTh.fr]

The TopEffTh model is implemented in the unitary gauge.
=== Validation ===

The cross-sections ([/attachment/wiki/TopEffTh/TEttbar.nb TEttbar.nb] and [/attachment/wiki/TopEffTh/singletop.nb singletop.nb]) and the decay rate ([/attachment/wiki/TopEffTh/topdecay.nb topdecay.nb]) analytic expressions have been computed with FeynArts and FormCalc and compared with the results of [http://inspirehep.net/record/865887&FORMAT=WWW&SEQUENCE= Phys.Rev.
