Heterotic AdS_3/CFT_2 duality with (0,4) spacetime supersymmetry
Stefan Hohenegger, Christoph A. Keller, Ingo Kirsch
We discuss the AdS_3/CFT_2 duality of a heterotic three-charge model with (0,4) target space supersymmetry. The worldsheet theory for heterotic strings on the AdS_3 x S^3/Z_N x T^4…
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…
A Generalization of Slavnov-Extended Non-Commutative Gauge Theories
Daniel N. Blaschke, Stefan Hohenegger
We consider a non-commutative U(1) gauge theory in 4 dimensions with a modified Slavnov term which looks similar to the 3-dimensional BF model. In choosing a space-like axial gauge…
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…
Gauge (in)dependence and UV/IR mixing
M. Attems, D. N. Blaschke, S. Hohenegger +2
The gauge independence in connection with the UV/IR-mixing is discussed with the help of the non-commutative U(1)-gauge field model proposed by A. A. Slavnov with two different gau…
