In these proceedings we explore the use of (non-linear) electroweak chiral Lagrangians for the description of possible beyond the Standard Model (BSM) strong dynamics in the electroweak (EW) sector. Experimentally one observes an approximate EW symmetry breaking pattern S U(2)L ×S U(2)R/S U(2)L+R. Quantum Chromodynamics (QCD) shows a similar chiral structure [1] and, in spite of the differences (in the EW theory S U(2)L × U(1)Y is gauged), it has served for years as a guide for this type of studies [2–4]. Examples of one-loop computations in the low-energy effective theory and the theory including the first vector (V) and axial-vector (A) resonances are provided, yielding, respectively, predictions for γγ → ZLZL, WL+ WL− and the oblique parameters S and T.
