Asymmetric Higgs Sector and Neutrino Mass in an SU(2)_R Model

The asymmetric Higgs sector of one $SU(2{)}_L\times SU(2{)}_R$ bidoublet $({\varphi }_1^0,{\varphi }_1^{-};{\varphi }_2^{+},{\varphi }_2^0)$ and one $SU(2{)}_R$ doublet [but no $SU(2{)}_L$ doublet] is considered in a nonsupersymmetric left-right extension of the standard model (SM) of particle interactions. The inverse seesaw mechanism for neutrino mass is naturally implemented with the addition of fermion singlets, allowing thereby the possibility of breaking $SU(2{)}_R$ at the TeV scale. In the limit $v_2=<{\varphi }_2^0>=0$, the unavoidable flavor-changing neutral Higgs couplings to quarks are studied and shown to be naturally suppressed in $K-\bar{K}$ and $B-\bar{B}$ mixing, as well as in $b \to s \gamma$. All particles are consistent with having masses less than 1 TeV, and could be observable at the Large Hadron Collider (LHC).
