A Renormalisation Group Equation Study of the Scalar Sector of the Minimal B-L Extension of the Standard Model
arXiv:1004.3039 · doi:10.1103/PhysRevD.82.055018
Abstract
We present the complete set of Renormalisation Group Equations (RGEs) at one loop for the non-exotic minimal U(1) extension of the Standard Model (SM). It includes all models that are anomaly-free with the SM fermion content augmented by one Right-Handed (RH) neutrino per generation. We then pursue the numerical study of the pure B-L model, deriving the triviality and vacuum stability bounds on an enlarged scalar sector comprising one additional Higgs singlet field with respect to the SM.
