We first review how to stabilise all the geometric and gauge bundle moduli in a supersymmetric way by including fractional fluxes, the requirement of a holomorphic gauge bundle, D-terms, higher order perturbative contributions to the superpotential as well as non-perturbative and threshold effects. We then show that the inclusion of α′ corrections to the Kähler potential leads to new stable Minkowski (or de Sitter) vacua where the complex structure moduli and the dilaton are fixed supersymmetrically at leading order, while the stabilisation of the Kähler moduli at a lower scale leads to spontaneous breaking supersymmetry. 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. We also provide a dynamical derivation of anisotropic compactifications with stabilised moduli which allow for perturbative gauge coupling unification around 1016 GeV. The value of the gravitino mass can be anywhere between the GUT and the TeV scale depending on the stabilisation of the complex structure moduli. In general, these are fixed by turning on background fluxes, leading to a gravitino mass around the GUT scale since the heterotic three-form flux does not contain enough freedom to tune the superpotential to small values. Moreover accommodating the observed value of the cosmological constant is a challenge. Low-energy supersymmetry could instead be obtained by focusing on particular Calabi-Yau constructions where the gauge bundle is holomorphic only at a point-like sub-locus of complex structure moduli space, or situations with a small number of complex structure moduli (like orbifold models), since in these cases one may fix all the moduli without turning on any quantised background flux. However obtaining the right value of the cosmological constant is even more of a challenge in these cases. Another option would be to focus on compactifications on non-complex manifolds, since these allow for new geometric fluxes which could be used to tune the superpotential as well as the cosmological constant, even if the moduli space of these manifolds is presently only poorly understood. 000155276 536__ $$0G:(DE-HGF)POF2-514$$a514 - Theoretical Particle Physics (POF2-514)$$cPOF2-514$$fPOF II$$x0 000155276 588__ $$aDataset connected to CrossRef, bib-pubdb1.desy.de 000155276 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000155276 7001_ $$0P:(DE-HGF)0$$aAlwis, S. de$$b1 000155276 7001_ $$0P:(DE-H253)PIP1013212$$aWestphal, A.$$b2 000155276 773__ $$0PERI:(DE-600)2027350-2$$a10.1007/JHEP10(2013)199$$gVol. 2013, no. 10, p. 199$$p199$$tJournal of high energy physics$$v2013$$x1029-8479$$y2013 000155276 8564_ $$uhttps://bib-pubdb1.desy.de/record/155276/files/art_10.1007_JHEP10%282013%29199.pdf$$yOpenAccess 000155276 8564_ $$uhttps://bib-pubdb1.desy.de/record/155276/files/art_10.1007_JHEP10%282013%29199.gif?subformat=icon$$xicon$$yOpenAccess 000155276 8564_ $$uhttps://bib-pubdb1.desy.de/record/155276/files/art_10.1007_JHEP10%282013%29199.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000155276 8564_ $$uhttps://bib-pubdb1.desy.de/record/155276/files/art_10.1007_JHEP10%282013%29199.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000155276 8564_ $$uhttps://bib-pubdb1.desy.de/record/155276/files/art_10.1007_JHEP10%282013%29199.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000155276 8564_ $$uhttps://bib-pubdb1.desy.de/record/155276/files/art_10.1007_JHEP10%282013%29199.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000155276 909CO $$ooai:bib-pubdb1.desy.de:155276$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000155276 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1010796$$aExternes Institut$$b0$$kExtern 000155276 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1013212$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000155276 9132_ $$0G:(DE-HGF)POF3-611$$1G:(DE-HGF)POF3-610$$2G:(DE-HGF)POF3-600$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Universum$$vFundamental Particles and Forces $$x0 000155276 9131_ $$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$$x0 000155276 9141_ $$y2013 000155276 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000155276 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000155276 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000155276 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000155276 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000155276 915__ $$0StatID:(DE-HGF)0010$$2StatID$$aJCR/ISI refereed 000155276 915__ $$0StatID:(DE-HGF)1020$$2StatID$$aDBCoverage$$bCurrent Contents - Social and Behavioral Sciences 000155276 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000155276 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000155276 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000155276 915__ $$0LIC:(DE-HGF)CCBY3$$2HGFVOC$$aCreative Commons Attribution CC BY 3.0 000155276 9201_ $$0I:(DE-H253)T-20120731$$kT$$lTheorie-Gruppe$$x0 000155276 980__ $$ajournal 000155276 980__ $$aVDB 000155276 980__ $$aUNRESTRICTED 000155276 980__ $$aintrep 000155276 980__ $$aI:(DE-H253)T-20120731 000155276 9801_ $$aFullTexts
