abstract = {We perform a systematic analysis of moduli stabilization
for weakly coupled heterotic string theory compactified on
smooth Calabi-Yau three-folds. We focus on both
supersymmetric and supersymmetry breaking vacua of generic
(0,2) compactifications obtained by minimising the total (F
+ D)-term scalar potential. After reviewing how to stabilise
all the geometric moduli in a supersymmetric way by
including fractional fluxes, non-perturbative and threshold
effects, we show that the inclusion of $\alpha'$ corrections
leads to new de Sitter or nearly Minkowski vacua which break
supersymmetry spontaneously. The minimum lies at moderately
large volumes of all the geometric moduli, at perturbative
values of the string coupling and at the right
phenomenological value of the GUT gauge coupling. However
the structure of the heterotic 3-form flux used for complex
structure moduli stabilization does not contain enough
freedom to tune the superpotential. This results in the
generic prediction of high-scale supersymmetry breaking
around the GUT scale. We finally provide a dynamical
derivation of anisotropic compactifications with stabilized
moduli which allow for perturbative gauge coupling
unification around $10^16$ GeV.},
