Constraints on the excitations in the strongly coupled standard model

Abstract

The strongly coupled standard model predicts a rich spectrum of excited states at the Fermi scale. We study the first radial excitations of the vector-bosons. The inclusion of these new states affects the low-energy phenomenology of the model. We put constraints on the effective couplings by performing a global fit with the electroweak observables, and we find that the excitations have to be rather decoupled from the low-energy states.
