Dualities of Deformed SCFTs from Link Monodromy on D3-brane States
Antonella Grassi, James Halverson, Fabian Ruehle +1
We study D3-brane theories that are dually described as deformations of two different superconformal theories with massless monopoles and dyons. These arise at the…
String Theory and the Dark Glueball Problem
James Halverson, Brent D. Nelson, Fabian Ruehle
We study cosmological constraints on dark pure Yang-Mills sectors. Dark glueballs are overproduced for large regions of ultraviolet parameter space. The problem may be alleviated i…
de Sitter vacua and supersymmetry breaking in six-dimensional flux compactifications
Wilfried Buchmuller, Markus Dierigl, Fabian Ruehle +1
We consider six-dimensional supergravity with Abelian bulk flux compactified on an orbifold. The effective low-energy action can be expressed in terms of N=1 chiral moduli superfie…
de Sitter vacua from an anomalous gauge symmetry
Wilfried Buchmuller, Markus Dierigl, Fabian Ruehle +1
We find a new class of metastable de Sitter solutions in compactifications of six-dimensional supergravity motivated by type IIB or heterotic string vacua. Two Fayet-Iliopoulos ter…
Line bundle embeddings for heterotic theories
Stefan Groot Nibbelink, Fabian Ruehle
In heterotic string theories consistency requires the introduction of a non-trivial vector bundle. This bundle breaks the original ten-dimensional gauge groups $\text{E}_8\times\te…
