Compactifications of Type II supergravities in superspace [PDF]

open access: yesJournal of High Energy Physics
We propose a way to describe compactifications of Type II supergravities with fluxes directly from superspace. The on-shell supergravity constraints used are the ones that arise naturally from the pure spinor superstring.

Black branes in flux compactifications [PDF]

open access: yes, 2013
We construct charged black branes in type IIA flux compactifications that are dual to (2+1)-dimensional field theories at finite density. The internal space is a general Calabi-Yau manifold with fluxes, with internal dimensions much smaller than the AdS radius.

Maximal supergravity from IIB flux compactifications [PDF]

open access: green, 2004
Using a recently proposed group-theoretical approach, we explore novel gaugings of maximal supergravity in four dimensions with gauge group embeddings that can be generated by fluxes of IIB string theory. The corresponding potentials are positive without

Proton decay in flux compactifications

open access: yesJournal of High Energy Physics, 2019
We study proton decay in a six-dimensional orbifold GUT model with gauge group SO(10)×U(1) A . Magnetic U(1) A flux in the compact dimensions determines the multiplicity of quark-lepton generations, and it also breaks supersymmetry by giving universal ...

Noncommutative compactifications of type I strings on tori with magnetic background flux [PDF]

open access: bronze, 2000
We construct six- and four-dimensional toroidal compactifications of the Type I string with magnetic flux on the D-branes. The open strings in this background probe a noncommutative internal geometry.

Geometric Algebra Techniques in Flux Compactifications [PDF]

open access: yesAdvances in High Energy Physics, 2016
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 ...

Comments on heterotic flux compactifications [PDF]

open access: bronze, 2006
In heterotic flux compactification with supersymmetry, three different connections with torsion appear naturally, all in the form $\omega+a H$. Supersymmetry condition carries $a=-1$, the Dirac operator has $a=-1/3$, and higher order term in the ...

SUSY phenomenology of KKLT flux compactifications [PDF]

open access: bronze, 2005
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.

DWSB in heterotic flux compactifications [PDF]

open access: hybrid, 2010
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

Superpotentials from flux compactifications of M-theory [PDF]

open access: green, 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
