Extra Matter at Low Energy
Abstract
Assuming that the Standard Model arises from the E8 × E8 Heterotic Superstring, we try to solve the discrepancy between the unification scale predicted by this theory (≈ gGUT × 5.27 · 1017 GeV) and the value deduced from LEP experiments (≈ 2 · 1016 GeV). This will allow us to predict the presence at low energies of three generations of supersymmetric Higgses and vector-like colour triplets.
