Model Building and Phenomenology of Flux-Induced Supersymmetry Breaking on D3-branes

, 2004
We study supersymmetry breaking effects induced on D3-branes at singularities by the presence of NSNS and RR 3-form fluxes. First, we discuss some local constructions of chiral models from D3-branes at singularities, as well as their global embedding in ...

Lectures on Gauged Supergravity and Flux Compactifications [PDF]

, 2008
The low-energy effective theories describing string compactifications in the presence of fluxes are so-called gauged supergravities: deformations of the standard abelian supergravity theories. The deformation parameters can be identified with the various

AdS Strings with Torsion: Non-complex Heterotic Compactifications [PDF]

, 2005
Combining the effects of fluxes and gaugino condensation in heterotic supergravity, we use a ten-dimensional approach to find a new class of four-dimensional supersymmetric AdS compactifications on almost-Hermitian manifolds of SU(3) structure ...

Topological data analysis for the string landscape

Journal of High Energy Physics, 2019
Persistent homology computes the multiscale topology of a data set by using a sequence of discrete complexes. In this paper, we propose that persistent homology may be a useful tool for studying the structure of the landscape of string vacua. As a scaled-

Model Building with F-Theory

, 2011
Despite much recent progress in model building with D-branes, it has been problematic to find a completely convincing explanation of gauge coupling unification.

Superpotentials from flux compactifications of M-theory

, 2004
In flux compactifications of M-theory a superpotential is generated whose explicit form depends on the structure group of the 7-dimensional internal manifold. In this note, we discuss superpotentials for the structure groups: G_2, SU(3) or SU(2). For the
