CP-violation from spin-1 resonances in a left-right dynamical Higgs context. (English) Zbl 1345.81146

Summary: 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 \(\mathrm{SU}(2)_{L} \otimes \mathrm{SU}(2)_{R}\otimes U(1)_{B-L}\), 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 \(p^{4}\)-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 \(h \to ZZ^\ast\to 4l\) that are briefly analysed. The final relevant set of effective operators have also been identified at low energies.
