The family problem: hints from heterotic line bundle models

Abstract:

Within the class of heterotic line bundle models, we argue that (Formula presented.) vacua which lead to a small number of low-energy chiral families are preferred. By imposing an upper limit on the volume of the internal manifold, as required in order to obtain finite values of the four-dimensional gauge couplings, and validity of the supergravity approximation we show that, for a given manifold, only a finite number of line bundle sums are consistent with supersymmetry. By explicitly scanni...
