Supersymmetric SU(5) GUT with Stabilized Moduli
Ignatios Antoniadis, Alok Kumar, Binata Panda
We construct a minimal example of a supersymmetric grand unified model in a toroidal compactification of type I string theory with magnetized D9-branes. All geometric moduli are st…
Anomaly induced effects in a magnetic field
Ignatios Antoniadis, Alexey Boyarsky, Oleg Ruchayskiy
We consider a modification of electrodynamics by an additional light massive vector field, interacting with the photon via Chern-Simons-like coupling. This theory predicts observab…
Harmonicity in N=4 supersymmetry and its quantum anomaly
I. Antoniadis, S. Hohenegger, K. S. Narain +1
The holomorphicity property of N=1 superpotentials or of N=2 F-terms involving vector multiplets is generalized to the case of N=4 1/2-BPS effective operators defined in harmonic s…
Topological Amplitudes and Physical Couplings in String Theory
I. Antoniadis, S. Hohenegger
In these lectures, we review the main properties of the topological theory obtained by twisting the N=2 two-dimensional superconformal algebra, associated to supersymmetric string…
