Abstract

The asymmetric Higgs sector of one SU(2)L×SU(2)RSU(2)_L \times SU(2)_R bidoublet (ϕ10,ϕ1;ϕ2+,ϕ20)(\phi_1^0,\phi_1^-;\phi_2^+,\phi_2^0) and one SU(2)RSU(2)_R doublet [but no SU(2)LSU(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)RSU(2)_R at the TeV scale. In the limit v2=<ϕ20>=0v_2 = < \phi_2^0 > = 0, the unavoidable flavor-changing neutral Higgs couplings to quarks are studied and shown to be naturally suppressed in KKˉK-\bar{K} and BBˉB-\bar{B} mixing, as well as in bsγb \to s \gamma. All particles are consistent with having masses less than 1 TeV, and could be observable at the Large Hadron Collider (LHC).
