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. 000152238 536__ $$0G:(DE-HGF)POF2-514$$a514 - Theoretical Particle Physics (POF2-514)$$cPOF2-514$$fPOF II$$x0 000152238 588__ $$aDataset connected to 000152238 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000152238 7001_ $$0P:(DE-HGF)0$$ade Alwis, Senarath$$b1 000152238 7001_ $$0P:(DE-H253)PIP1013212$$aWestphal, Alexander$$b2 000152238 8564_ $$uhttps://bib-pubdb1.desy.de/record/152238/files/DESY-2013-00139.pdf$$yOpenAccess 000152238 8564_ $$uhttps://bib-pubdb1.desy.de/record/152238/files/DESY-2013-00139.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000152238 8564_ $$uhttps://bib-pubdb1.desy.de/record/152238/files/DESY-2013-00139.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000152238 8564_ $$uhttps://bib-pubdb1.desy.de/record/152238/files/DESY-2013-00139.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000152238 909CO $$ooai:bib-pubdb1.desy.de:152238$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000152238 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1013212$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000152238 9131_ $$0G:(DE-HGF)POF2-514$$1G:(DE-HGF)POF2-510$$2G:(DE-HGF)POF2-500$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bStruktur der Materie$$lElementarteilchenphysik$$vTheoretical Particle Physics$$x0 000152238 9141_ $$y2013 000152238 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000152238 9201_ $$0I:(DE-H253)T-20120731$$kT$$lTheorie-Gruppe$$x0 000152238 980__ $$apreprint 000152238 980__ $$aVDB 000152238 980__ $$aUNRESTRICTED 000152238 980__ $$aFullTexts 000152238 980__ $$aintrep 000152238 980__ $$aI:(DE-H253)T-20120731 000152238 9801_ $$aFullTexts
