Gauge Thresholds and Kaehler Metrics for Rigid Intersecting D-brane Models
Ralph Blumenhagen, Maximilian Schmidt-Sommerfeld
The gauge threshold corrections for globally consistent Z2 x Z2' orientifolds with rigid intersecting D6-branes are computed. The one-loop corrections to the holomorphic gauge kine…
D-brane Instantons in 4D Supersymmetric String Vacua
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +1
We review some aspects of D-instantons in intersecting D-brane models. In particular, we present applications of the recently proposed instanton calculus to computations of charged…
Instantons and Holomorphic Couplings in Intersecting D-brane Models
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +1
We clarify certain aspects and discuss extensions of the recently introduced string D-instanton calculus (hep-th/0609191). The one-loop determinants are related to one-loop open st…
Thresholds for Intersecting D-branes Revisited
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +1
Gauge threshold corrections for intersecting D6-brane string models on toroidal orbifold backgrounds are reconsidered. Both by dimensionally regularising the appearing open string…
