Direct searches for New Physics states have given so far negative results, so there is a mass gap between SM fields and possible new fields. This mass gap justifies the use of electroweak effective Lagrangians for current energies. Implications of new, higher scales can be analyzed through next-to-leading order corrections of the electroweak effective theory. There are two main ingredients for this analysis. Firstly, a non-linear realization of the electroweak symmetry breaking with a singlet Higgs and a strongly-coupled UV-completion at low energies is assumed. And secondly, a high-energy Lagrangian which incorporates a set of new heavy states is considered. By integrating out these heavy resonances, we study the pattern of low-energy constants among the light fields, which are generated by these massive states.
