We discuss perturbative four-dimensional compactifications of both the SO(32) heterotic and the type-I string on smooth Calabi-Yau manifolds endowed with general non-abelian and abelian bundles. We analyse the generalized Green-Schwarz mechanism for multiple anomalous U(1) factors and derive the generically non-universal one-loop threshold corrections to the gauge kinetic function as well as the one-loop corrected Fayet-Iliopoulos terms. The latter can be interpreted as a stringy one-loop…

Heterotic vacua from general (non-) Abelian bundles
We report on the construction of four-dimensional string vacua by considering general abelian and non-abelian bundles on an internal Calabi-Yau for both heterotic theories. The structure of the

Calabi-Yau compactifications of non-supersymmetric heterotic string theory

The compactification from the 11-dimensional Horava-Witten orbifold to 5-dimensional heterotic M-theory on a Schoen Calabi-Yau threefold is reviewed, as is the specific S U ( 4 ) vector bundle

Abstract We examine heterotic M-theory compactified on a Calabi–Yau manifold with an additional parallel M5-brane. The dominant non-perturbative effect stems from open membrane instantons connecting

We present a class of chiral non-supersymmetric D = 4 field theories in which quadratic divergences appear only at two loops. They may be depicted as ``SUSY quivers'' in which the nodes represent a
