Flux compactifications and naturalness [PDF]
Free massless scalars have a shift symmetry. This is usually broken by gauge and Yukawa interactions, such that quantum corrections induce a quadratically divergent mass term.

Nongeometric flux compactifications [PDF]
We investigate a simple class of type II string compactifications which incorporate nongeometric "fluxes" in addition to "geometric flux" and the usual H-field and R-R fluxes. These compactifications are nongeometric analogues of the twisted torus.

Lobotomy of flux compactifications [PDF]
A bstractWe provide the dictionary between four-dimensional gauged supergravity and type II compactifications on $ \mathbb{T} $6 with metric and gauge fluxes in the absence of supersymmetry breaking sources, such as branes and orientifold planes ...

Threshold corrections in heterotic flux compactifications [PDF]
We compute the one-loop threshold corrections to the gauge and gravitational couplings for a large class of N = 2 $$ \mathcal{N}=2 $$ non-Kähler heterotic compactifications with three-form flux, consisting in principal two-torus bundles over K3 surfaces.

DWSB in heterotic flux compactifications [PDF]
We address the construction of non-supersymmetric vacua in heterotic compactifications with intrinsic torsion and background fluxes. In particular, we implement the approach of domain-wall supersymmetry breaking (DWSB) previously developed in the context

Flavor mixings in flux compactifications [PDF]
A multiplicity of quark-lepton families can naturally arise as zero-modes in flux compactifications. The flavour structure of quark and lepton mass matrices is then determined by the wave function profiles of the zero-modes. We consider a supersymmetric $

Three-forms in supergravity and flux compactifications [PDF]
We present a duality procedure that relates conventional four-dimensional matter-coupled $$\mathcal{N}=1$$ N = 1 supergravities to dual formulations in which auxiliary fields are replaced by field strengths of gauge three-forms.

SUSY phenomenology of KKLT flux compactifications [PDF]
We study SUSY phenomenology of the KKLT (Kachru-Kallosh-Linde-Trivedi) scenario of string theory compactifications with fluxes. This setup leads to a specific pattern of soft masses and distinct phenomenological properties.

Special points of inflation in flux compactifications [PDF]
We study the realization of axion inflation models in the complex structure moduli spaces of Calabi–Yau threefolds and fourfolds. The axions arise close to special points of these moduli spaces that admit discrete monodromy symmetries of infinite order ...

Geometric Algebra Techniques in Flux Compactifications [PDF]
We study “constrained generalized Killing (s)pinors,” which characterize supersymmetric flux compactifications of supergravity theories. Using geometric algebra techniques, we give conceptually clear and computationally effective methods for translating ...
