Abstract
The possibility of superstring compactification on Calabi-Yau manifolds is analyzed in the light of recent work by Grisaru, van de Ven and Zanon, and by Freeman and Pope. It is shown that despite the appearance of non-zero β-function at the four-loop order, a conformally invariant supersymmetric σ-model on a Calabi-Yau manifold can be constructed. The background metric is not Ricci flat, but is related to the Ricci-flat metric through a (non-local) field redefinition.
