A modified BESS model as the effective description of strong electroweak symmetry breaking
Original language description
Facing the plethora of alternative hypotheses for the mechanism of electroweak symmetry breaking (ESB) it is highly desirable to typify its phenomenology using the effective Lagrangians. The BESS (Breaking Electroweak Symmetry Strongly) model is one of them. The model couples the vector resonances universally to all Standard model (SM) fermion generations. We have modified the model by allowing direct interactions of the vector triplet with the third quark generation only. This is motivated by the extraordinary mass of the top quark which is close to the ESB scale. In addition, we have introduced new Lagrangian terms admitted by the model's symmetries. Our modifications of the BESS model can significantly relax the low-energy limits on the original BESS model's parameters. Further, due to the modifications the new vector resonances became narrower. Here, we present the new model's basic phenomenology and compare it to the original BESS model.
