摘要：

A methodology for computing the massless spectrum of heterotic vacua with Wilson lines is presented. This is applied to a specific class of vacua with holomorphic SU(5)-bundles over torus-fibered Calabi-Yau threefolds with fundamental group Z(2). These vacua lead to low-energy theories with the standard model gauge group SU(3)(C) x SU(2)(L) x U(1)(Y) and three families of quark/leptons. The massless spectrum is computed, including the multiplicity of Higgs doublets. (c) 2005 Elsevier B.V All rights reserved.
