Matrix Factorizations, Massey Products and F-Terms for Two-Parameter Calabi-Yau Hypersurfaces

Johanna Knapp, Emanuel Scheidegger

We discuss B-type tensor product branes in mirrors of two-parameter Calabi-Yau hypersurfaces, using the language of matrix factorizations. We determine the open string moduli of th…

On Slow-roll Moduli Inflation in Massive IIA Supergravity with Metric Fluxes

Raphael Flauger, Sonia Paban, Daniel Robbins +1

We derive several no-go theorems in the context of massive type IIA string theory compactified to four dimensions in a way that, in the absence of fluxes, preserves N=1 supersymmet…

The Stress-Energy Tensor of Flavor Fields from AdS/CFT

Andreas Karch, Andy O'Bannon, Ethan Thompson

We use the AdS/CFT correspondence to study the transport properties of massive N=2 hypermultiplet fields in an N=4 SU(Nc) super-Yang-Mills theory plasma in the large Nc, large 't H…

Gauge Coupling Unification in F-theory GUT Models

Ralph Blumenhagen

We investigate gauge coupling unification for F-theory respectively Type IIB orientifold constructions of SU(5) GUT theories with gauge symmetry breaking via non-trivial hypercharg…

On the Yang-Mills two-loop effective action with wordline methods

Jan M. Pawlowski, Michael G. Schmidt, Jian-Hui Zhang

We derive the two-loop effective action for covariantly constant field strength of pure Yang-Mills theory in the presence of an infrared scale. The computation is done in the frame…

Toward a Holographic Model of Superconducting Fermions

Andy O'Bannon

We use the AdS/CFT correspondence to study N=4 supersymmetric SU(Nc) Yang-Mills theory, in the limits of large Nc and large 't Hooft coupling, coupled to a number Nf of massless hy…
