22 | | This model is an simplified version of the VLQ FeynRules model, including a single vector-like (X,T) doublet (Q=5/3, 2/3), with non-zero mixings to the first and third generation SM quarks [1] [2], as described in the dedicated study [3]. The pattern of allowed couplings is such that X decays 100% to W bosons, while T decays 50% in Z and 50% in H bosons, in the asymptotic limit where their (degenerate) masses go to infinity. The corresponding FeynRules implementation is based on the VLQ.fr model description, which provides a direct connection between experimental observables and the new quark couplings. The model file [attachment:xtdoubletvl.fr.zip] adds the following interactions to the SM Lagrangian:[[Image(XTDoublet.png)]] |
