Abstract

We consider the possibility of breaking a rank-six superstring model to the rank-four standard model. In particular, we point out the difficulties in generating two vacuum expectation values for the two standard model singlets contained in the 27 of E₆. Although one expectation value is compatible with low energy phenomenology, a vev for v^c is problematic because of the absence of large neutrino masses and / or flavor changing neutral currents. We show that even simple models containing extra fields from incomplete multiplets or E₆ singlets do not resolve these problems.
