Non-perturbative Yukawa Couplings from String Instantons
Ralph Blumenhagen, Mirjam Cvetic, Dieter Lust +2
Non-perturbative D-brane instantons can generate perturbatively absent though phenomenologically relevant couplings for Type II orientifold compactifications with D-branes. We disc…
Resolved Toroidal Orbifolds and their Orientifolds
D. Lust, S. Reffert, E. Scheidegger +1
We discuss the resolution of toroidal orbifolds. For the resulting smooth Calabi-Yau manifolds, we calculate the intersection ring and determine the divisor topologies. In a next s…
F-theory Flux, Destabilization of Orientifolds and Soft Terms on D7--Branes
D. Lust, P. Mayr, S. Reffert +1
We use F-theory to derive a general expression for the flux potential of type II compactifications with D7/D3 branes, including open string moduli and 2-form fluxes on the branes.…
Scattering of Gauge, Matter, and Moduli Fields from Intersecting Branes
D. Lust, P. Mayr, R. Richter +1
We calculate various tree-level (disk) scattering amplitudes involving gauge, matter and moduli fields in type IIB toroidal orbifold/orientifold backgrounds with D9,D5 respectively…
Gauge Threshold Corrections in Intersecting Brane World Models
D. Lust, S. Stieberger
We calculate the one-loop corrections to gauge couplings in N=1 supersymmetric brane world models, which are realized in an type IIA orbifold/orientifold background with several st…
