  Accepting that there is a mass gap above the electroweak scale, the
Electroweak Effective Theory (EWET) is an appropriate tool to describe this
situation. Since the EWET couplings contain information on the unknown
high-energy dynamics, we consider a generic strongly-coupled scenario of
electroweak symmetry breaking, where the known particle fields are coupled to
heavier states. Then, and by integrating out these heavy fields, we study the
tracks of the lightest resonances into the couplings. The determination of the
low-energy couplings (LECs) in terms of resonance parameters can be made more
precise by considering a proper short-distance behaviour on the Lagrangian with
heavy states, since the number of resonance couplings is then reduced. Notice
that we adopt a generic non-linear realization of the electroweak symmetry
breaking with a singlet Higgs.
