Abstract

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)LSU(2)RU(1)BLSU(2)_L\otimes SU(2)_R\otimes 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 p4p^4-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 hZZ4lh\rightarrow ZZ^*\rightarrow 4\,l that are briefly analysed. The final relevant set of effective operators have also been identified at low energies.
