Fermion condensates and weak symmetry breaking in a superstring-based model

We start with the gauge group ${\mathrm{SU}\mathrm{}\left(3\right)\mathrm{}}_C\times {\mathrm{SU}\mathrm{}\left(2\right)\mathrm{}}_L\times {\mathrm{U}\mathrm{}\left(1\right)\mathrm{}}_R\times {\mathrm{U}\mathrm{}\left(1\right)\mathrm{}}_N\left(\equiv G_{3211}\right)$, which is a rank-five subgroup of ${\mathrm{E}}_6$. We include chiral-fermion-condensate terms in the effective four-dimensional Lagrangian derived from superstrings, and discuss how this condensation can be responsible for weak symmetry breaking at a scale of 100 GeV. One experimental effect of the above will be the nonobservation of light Higgs scalars of the Salam-Weinberg model, although the other results of the same remain unchanged.
