Dynamical left-right symmetry breaking.
We study a left–right symmetric model which contains only elementary gauge boson and fermion fields and no scalars. The phenomenologically required symmetry breaking emerges dynamically leading to a composite Higgs sector with a renormalizable effective Lagrangian. We discuss the pattern of symmetry breaking and phenomenological consequences of this scenario. It is shown that a viable top quark...
متن کاملLeft-right Gauge Symmetry at the Tev Energy Scale *
Two first examples beyond the standard model are given which exhibit left-right symmetry (g L = g R) and supersymmetry at a few TeV, together with gauge-coupling unification at around 10 16 GeV.
متن کاملLow Energy Consequences from Supersymmetric Models with Left-right Symmetry
We consider several low energy consequences arising from a class of supersymmetric models based on the gauge groups SU(2)L ×SU(2)R ×U(1)B−L and SU(4)C × SU(2)L × SU(2)R in which the gauge hierarchy and μ problems have been resolved. There are important constraints on the MSSM parameters tan β(≃ mt/mb), B and μ, and we discuss how they are reconciled with radiative electroweak breaking. We also ...
متن کاملA Dynamical Left–right Symmetry Breaking Model *
Left–right symmetry breaking in a model with composite Higgs scalars is discussed. It is assumed that the low–energy degrees of freedom are just fermions and gauge bosons and that the Higgs bosons are generated dynamically through a set of gauge– and parity–invariant 4-fermion operators. It is shown that in a model with composite bi-doublet and two triplet scalars there is no parity breaking at...
متن کاملLeft-right symmetry and supersymmetric unification.
The existence of an SU(3)×SU(2)L×SU(2)R×U(1) gauge symmetry with gL = gR at the TeV energy scale is shown to be consistent with supersymmetric SO(10) grand unification at around 10 GeV if certain new particles are assumed. The additional imposition of a discrete Z2 symmetry leads to a generalized definition of R parity as well as highly suppressed Majorana neutrino masses. Another model based o...
