Models/TopEffTh
v7 v8 15 15 This !MadGraph5 model is the implementation of the top effective field theory described in arXiv:1008.3869 [hepph]. Namely, the model contains all the dimension six operators that are interfering with the leading treelevel SM amplitude for the top decay and both single top and top pair productions. This model is particularly suited to study the largest effects of nonresonant new physics (e.g. composite top and Higgs) in a model independent way. All the fourfermion operators are flavor diagonal and universal for the two lightest generations. 16 16 17 The fourfermion operators have been implemented using heavy vectors since they are not yet available in !MadGraph5. In consequence, the model should not be used for other processes than the top decay and single top and top pair productions because it can contain extra operators. For example, a heavy vector coupled to ttbar and ddbar will induce a ttbarddbar vertex as well as a 4top one. 18 19 Futher information can be found in the note included in the model directory. 17 Futher information can be found in [/attachment/wiki/Models/TopEffTh/note.pdf note.pdf]. 20 18
