School PHYSICS Abstract: The idea of with EW-$nu_R$ model with additional GeV scale mirror fermions and the extended scalar sector is very appealing. This model has a very rich scalar sector, consistent with various experimental constraints, predicts a 125 GeV scalar with the SM Higgs characteristics satisfying the current LHC Higgs boson data. A complex singlet scalar in this model helps to solve the strong-CP problem without an axion. In this work, we study the detailed scalar mass spectrum, having 125 GeV Higgs-like scalar, which is allowed by the present experimental constraints. Besides explaining the Higgs-like scalar, we find that the imag ... |
