The family problem: hints from heterotic line bundle models
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...
