CP-Violation from Spin-1 Resonances in a Left-Right Dynamical Higgs Context

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) circle times SU(2)(R) circle times 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 -> ZZ* -> 4l that are briefly analysed. The final relevant set of effective operators have also been identified at low energies.
