摘要： New physics field content in the nature, more specifically, from spin–1 resonances sourced by the extension of the SM local gauge symmetry to the larger local group SU(2)L⊗SU(2)R⊗U(1)B−L, may induce CP–violation signalling NP effects from higher energy regimes. In this work we completely list and study all the CP–violating operators up to the p4–order in the Lagrangian expansion, for a non–linear left–right electroweak chiral context and coupled to a light dynamical Higgs. Heavy right handed fields can be integrated out from the physical spectrum, inducing thus a physical impact in the effective gauge couplings, fermionic electric dipole moment, and CP-violation in the decay h → ZZ∗ → 4 l that are briefly analysed. The final relevant set of effective operators have also been identified at low energies.
