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 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…
Geometric transitions and integrable systems
Duiliu-Emanuel Diaconescu, Ron Donagi, Robbert Dijkgraaf +2
We consider {\bf B}-model large duality for a new class of noncompact Calabi-Yau spaces modeled on the neighborhood of a ruled surface in a Calabi-Yau threefold. The closed str…
Geometric Transitions and Mixed Hodge Structures
Duiliu-Emanuel Diaconescu, Ron Donagi, Tony Pantev
We formulate and prove a B-model disc level large N duality result for general conifold transitions between compact Calabi-Yau spaces using degenerations of Hodge structures.
A Vertex Formalism for Local Ruled Surfaces
Duiliu-Emanuel Diaconescu, Bogdan Florea, Natalia Saulina
We develop a vertex formalism for topological string amplitudes on ruled surfaces with an arbitrary number of reducible fibers embedded in a Calabi-Yau threefold. Our construction…
