The Effective MLRSM Model and Low-energy Observables

Abstract

We consider an effective Minimal Left–Right Symmetric Model. Instead of engaging all the dimension-6 operators, we choose only the relevant, in the limit that right-handed symmetry breaking scale is larger than the electroweak one, operators belonging to ϕ2X2 class. We adjudge the impact of those operators on the spectrum and vertices of the model, and then capture their contributions to the low-energy observables, e.g. , ρ,GF,ΘW, and oblique parameters S,T,U.
