A Truly Minimal Left-Right Symmetric Extension of the Standard Model
نویسنده
چکیده
By invoking the existence of a general custodial O(2) symmetry, a minimal Left-Right symmetric model based on the gauge group G = SU(2)L ⊗ SU(2)R ⊗ U(1)B−L is shown to require the existence of only two physical Higgs bosons. The lighter Higgs is predicted to have a small mass which could be evaluated by standard perturbation theory. The fermionic mass matrices are recovered by insertion of ad hoc fermion-Higgs interactions. The model is shown to be undistinguishable from the standard model at the currently reachable energies.

Fine tuning in the Standard Model and Beyond
The fine-tuning principles are examined to predict the top-quark and Higgs-boson masses. The modification of the Veltman condition based on the compensation of vacuum energies is developed. It is implemented in the Standard Model and in its minimal extension with two Higgs doublets and Left-Right symmetric Model. The top-quark and Higgs-boson couplings are fitted in the SM for the lowest ultrav...
متن کاملA construction of a minimal Higgs potential of left - right symmetric gauge model
We study non-zero vacuum expectation values (VEVs) of scalars of left-right symmetric model. These VEVs can be written in matrix forms in a SU(2)L ×SU(2)R basis. Such matrices manifest surviving symmetries at the end of left-right symmetry breaking. Then we go upwards in energy scale and construct a minimal left-right symmetric Higgs potential, using the Cayley-Hamilton theorem. This potential,...
متن کامل1 Extended electroweak models and their tests in future colliders
In this Thesis some possible tests of physics beyond the Standard Model in the next generation collider experiments are considered. The main emphasis is put on the processes which may be studied in the non-conventional ee, eγ and γγ operation modes of the next linear collider (NLC). The sensitivity of the NLC for testing the gauge boson self-interactions through the reaction eγ → Wν is investig...
متن کاملOn construction of a minimal scalar potential of left-right symmetric model
We start with VEVs of scalars of left-right symmetric model in standard matrix forms those manifest surviving symmetries at lower energies. Then we go upwards in energy scale and construct a minimal potential, using the Cayley-Hamilton theorem, relevant to full range of parameter space of the VEVs (any value of the VEVs). This procedure is complementary to the conventional procedure of writing ...
متن کاملEffects of the Parity-odd _singlet on -then = 1 Supergravity Theory within the Left-right Symmetric Model*
We study the N = 1 supergravity theory within the left-right symmetric model, based on the gauge symmetry sum x sum x U(~)B-L, when the parity-odd singlet field is added, in addition to the minimal set of Higgs fields. This model allows for a vacuum solution with the hierarchy ratio q = (rn~~/rn~~) > 1. Also, the gravitino mass is likely to set the scale of mw, rather than the one of mwR. These...
