Minimal Z' models and the 125 GeV Higgs boson

Abstract

The 1-loop renormalization group equations for the minimal Z' models encompassing a type-I seesaw mechanism are studied in the light of the 125 GeV Higgs boson discovery. This model is taken as a benchmark for the general case of singlet extensions of the standard model. The most important result is that negative scalar mixing angles are favoured with respect to positive values. Further, a minimum value for the latter exists, as well as a maximum value for the masses of the heavy neutrinos, depending on the vacuum expectation value of the singlet scalar.

12 pages, 4 figures. Corrected Eq.(8) and according references, affecting only heavy neutrino masses (values half than before). Other results unchanged
