Abstract

A simple phenomenological parametrization of the four-dimensional field theory arising from compactification of the ten-dimensional heterotic string is considered. Possible vacuum states of the four-dimensional theory are examined in the context of the "model" low-energy Lagrangian proposed by Witten. A large hierarchy between MP and m3/2 arises naturally for a large region of parameter space, with the compactification scale typically 0(1 − 10−2)and a vanishing cosmological constant. The presence of E6 singlet superfields with large nonperturbative masses (coming from world-sheet instantons) can drastically alter the hierarchy in certain cases, but nonetheless leads to acceptable low-energy phenomenology.
