22 | | This model is an simplified version of the VLQ FeynRules model, including a single vector-like B singlet quark (Q=-1/3), with non-zero mixings to the first and third generation SM quarks [1] [2] [3]. The pattern of allowed couplings is such that B decays 50% to W, 25% to Z and H bosons in the asymptotic limit where the mass M goes to infinity, in agreement with what is expected from the Goldstone equivalence theorem. 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:bsingletvl.fr.zip] adds the following interactions to the SM Lagrangian:[[Image(BSinglet2.png)]] |
