Minimal Supersymmetric $SU(4) \to SU(2)_L \to SU(2)_R$

We present a minimal string-inspired supersymmetric $SU(4) \times SU(2)_L potential in this model, based on a generalisation of that recently proposed by Dvali, Lazarides and Shafi. The model contains a global U(1) R-symmetry and reduces to the MSSM at low energies. However it improves on the MSSM s...

description We present a minimal string-inspired supersymmetric $SU(4) \times SU(2)_L potential in this model, based on a generalisation of that recently proposed by Dvali, Lazarides and Shafi. The model contains a global U(1) R-symmetry and reduces to the MSSM at low energies. However it improves on the MSSM since it explains the magnitude of its $\mu$ term and gives a prediction for $\tan \beta both `cold' and `hot' dark matter candidates. A period of hybrid inflation above the symmetry breaking scale is also possible in this model. Finally it suggests the existence of `heavy' charge $\pm e/6$ (colored) and $\pm e/2$ (color singlet) states.

The model contains a global U (1) R-symmetry and reduces to the MSSM at low energies. However it improves on the MSSM since it explains the magnitude of its μ term and gives a prediction for tan β ≃ m t / m b . It also predicts an essentially stable proton, and contains both `cold' and `hot' dark matter candidates. A period of hybrid inflation above the symmetry breaking scale is also possible in this model. Finally it suggests the existence of `heavy' charge ± e /6 (colored) and ± e /2 (color singlet) states.hep-ph/9711288CERN-TH-97-314BA-97-49CERN-TH-97-314BA-97-49oai:cds.cern.ch:3382701997-11-11
