Abstract:
We derive the Standard model gauge group together with chiral fermion generations from the heterotic string by turning on a Wilson line on a non-simply connected Calabi-Yau threefold with an SU(5) gauge group. For this we construct stable Z2{\bf Z_2}-invariant SU(4)×U(1)SU(4)\times U(1) bundles on an elliptically fibered cover Calabi-Yau threefold of special fibration type (the BB-fibration). The construction makes use of a modified spectral cover approach giving just invariant bundles.
