Strong coupling expansion of CalabiYau compactification
Abstract
In a certain strong coupling limit, compactification of the E_{8} × E_{8} heterotic string on a CalabiYau manifold X can be described by an elevendimensional theory compactified on X × S^{1}/ Z_{2}. In this limit, the usual relations among lowenergy gauge couplings hold, but the usual (problematic) prediction for Newton's constant does not. In this paper, the equations for unbroken supersymmetry are expanded to the first nontrivial order, near this limit, verifying the consistency of the description and showing how, in some cases, if one tries to make Newton's constant too small, strong coupling develops in one of the two E_{8}'s. The lower bound on Newton's constant (beyond which strong coupling develops) is estimated and is relatively close to the actual value.
