Top-BESS model and its phenomenology
Result description
We introduce the top-BESS model which is the effective description of the strong electroweak symmetry breaking with a single new SU(2)_{L+R} triplet vector resonance. The model is a modification of the BESS model in the fermion sector. The triplet couples to the third generation of quarks only. This approach reflects a possible extraordinary role of the top quark in the mechanism of electroweak symmetry breaking. The found low-energy limits on the model parameters provide a hope for sizable signals in the LHC Drell-Yan processes as well as in the s-channel production processes at the ILC. However, there are regions of the model parameter space where the interplay of the direct and indirect fermion couplings can hide the resonance peak in a scattering process even though the resonance exists and couples directly to top and bottom quarks.
