Metastable Quivers in String Compactifications
Duiliu-Emanuel Diaconescu, Ron Donagi, Bogdan Florea
We propose a scenario for dynamical supersymmetry breaking in string compactifications based on geometric engineering of quiver gauge theories. In particular we show that the runaw…
Black String Entropy and Fourier-Mukai Transform
Iosif Bena, Duiliu-Emanuel Diaconescu, Bogdan Florea
We propose a microscopic description of black strings in F-theory based on string duality and Fourier-Mukai transform. These strings admit several different microscopic description…
Stringy Instantons and Quiver Gauge Theories
Bogdan Florea, Shamit Kachru, John McGreevy +1
We explore contributions to the 4D effective superpotential which arise from Euclidean D3 branes (``instantons'') that intersect space-filling D-branes. These effects can perturb t…
Gauge-Mediated Supersymmetry Breaking in String Compactifications
Duiliu-Emanuel Diaconescu, Bogdan Florea, Shamit Kachru +1
We provide string theory examples where a toy model of a SUSY GUT or the MSSM is embedded in a compactification along with a gauge sector which dynamically breaks supersymmetry. We…
The Ruled Vertex and Nontoric del Pezzo Surfaces
Duiliu-Emanuel Diaconescu, Bogdan Florea
We construct the topological partition function of local nontoric del Pezzo surfaces using the ruled vertex formalism.
The Ruled Vertex and D-E Degenerations
Duiliu-Emanuel Diaconescu, Bogdan Florea
We compute all genus topological amplitudes on configurations of ruled surfaces obtained by resolving lines of D-E singularities in compact Calabi-Yau threefolds. We find that our…
