Chiral Dynamics beyond the Standard Model

Abstract : The SM Lagrangian without physical scalars is rewritten as the LO of a Low-Energy Effective Theory invariant under a higher non linear symmetry S_{nat} \supset SU(2)_W \times U(1)_Y. Soft breaking of S_{nat} defines a hierarchy of non standard effects dominated by universal couplings of right-handed quarks to W. The interface of corresponding EW tests with non perturbative QCD aspects is briefly discussed.
