Abstract

In the three-generation models with SUSY SO(10) or SU(5) GUTs derived from the (2, 0) compactification of E₈×E′₈ heterotic string, the massless matter field spectra at the GUT scale M_x and the breaking directions of GUT symmetries are discussed. A pseudo-left-right symmetric Pati-Salam model is naturally deduced in the SUSY SO(10) GUT and shown to have an interesting property, M_x≃M_P1, M_R≃10¹⁰ GeV and M_s (the scale of superpartner masses) ≃10⁴ GeV, as a result of the renormalization group equation analysis using the new precise LEP data.
