The muon g-2 in a SU(7) left-right symmetric model with mirror fermions
We have studied a left-right symmetric model with mirror fermions based in a grand unified SU(7) model in order to account for the muon anomaly. The Higgs sector of the model contains two Higgs doublets and the hierarchy condition υL ≪ υR can be achieved by using two additional Higgs singlets, one even and other odd under D-parity. We show that there is a wide range of values for the mass param...

متن کاملMirror Fermions in Noncommutative Geometry
In a recent paper we pointed out the presence of extra fermionic degrees of freedom in a chiral gauge theory based on Connes Noncommutative Geometry. Here we propose a mechanism which provides a high mass to these mirror states, so that they decouple from low energy physics. ∗E-mail: [email protected], [email protected], [email protected], [email protected] Recently in Ref.[1] we have pointed o...
متن کاملDynamical Symmetry Breaking with Mirror Fermions
Mirror fermions with masses around the weak scale could break dynamically the electro-weak symmetry if they were coupled with a new strong interaction. The purpose of this talk is to show what sort of dynamics are needed in order to render such theories phenomenologically viable.
متن کاملPhenomenology of Mirror Fermions in the Littlest Higgs Model with T-Parity
Little Higgs models are an interesting alternative to explain electroweak symmetry breaking without fine-tuning. Supplemented with a discrete symmetry (T-parity) constraints from electroweak precision data are naturally evaded and also a viable dark matter candidate is obtained. T-parity implies the existence of new (mirror) fermions in addition to the heavy gauge bosons of the little Higgs mod...
