Gaugino mass term for D-branes and Generalized Complex Geometry
Mariana Graña, Nicolas Kovensky, Ander Retolaza
We compute the four-dimensional gaugino mass for a Dp-brane extended in spacetime and wrapping a cycle on the internal geometry in a warped compactification with fluxes. Motivated…
Winding modes and the reflection symmetry in AdS
Sergio Iguri, Nicolas Kovensky, Leila Maestri +1
We compute the contact term of the two-point function for the SL()-WZNW model in the winding sector. After reviewing some generalities of the model and its Euclidean c…
Heavy Holographic QCD
Nicolas Kovensky, Andreas Schmitt
We study the phase structure of the Witten-Sakai-Sugimoto model in the plane of temperature and baryon chemical potential, including the effect of a nonzero current quark mass. Our…
Kähler moduli stabilization from ten dimensions
Iosif Bena, Mariana Graña, Nicolas Kovensky +1
We describe the back-reaction of gaugino condensates in supersymmetric AdS Type II String Theory compactifications with fluxes. We use generalized complex geometry to capture t…
