Minimal Left-Right Symmetric Dark Matter.
We show that left-right symmetric models can easily accommodate stable TeV-scale dark matter particles without the need for an ad hoc stabilizing symmetry. The stability of a newly introduced multiplet either arises accidentally as in the minimal dark matter framework or comes courtesy of the remaining unbroken Z_{2} subgroup of B-L. Only one new parameter is introduced: the mass of the new mul...
متن کاملDark-matter fermion from left-right symmetry
In an unconventional realization of left-right symmetry, the particle corresponding to the left-handed neutrino L [with SUð2ÞL interactions] in the right-handed sector, call it nR [with SUð2ÞR interactions], is not its Dirac mass partner, but a different particle which may be a dark-matter candidate. In parallel to leptogenesis in the SUð2ÞL sector, asymmetric production of nR may occur in the ...
متن کاملLeptogenesis in Minimal Left-Right Symmetric Models
We analyze lepton asymmetry induced in the decay of right–handed neutrinos in a class of minimal left–right symmetric models. In these models, which assume low energy supersymmetry, the Dirac neutrino mass matrix is proportional to the charged lepton mass matrix. As a result, lepton asymmetry is calculable in terms of 9 parameters, all measurable in low energy neutrino experiments. By solving t...
متن کاملPotential Minimization in Left-right Symmetric Models
We study the Higgs potentials in the Left-Right symmetric model for various choices of Higgs fields. We give emphasis to the cases when the Higgs field ξ = (2, 2, 15) is included to give the correct relations of quark masses and a singlet field η which breaks the left-right parity. As special cases we also include ξ = (2, 2, 15) and χ = (2, 2, 6) (which are interesting in the context of the thr...
متن کاملLeft-Right Symmetric Models in Noncommutative Geometries?
In the Standard Model of electro-weak and strong forces, parity is broken explicitly by the choice of inequivalent representations for leftand right-handed fermions. Within the frame work of Yang-Mills-Higgs models this is certainly an aesthetic draw back that physicists have tried to correct by the introduction of left-right symmetric models. These are Yang-Mills-Higgs models where parity is b...
