Relating prepotentials and quantum vacua of N=1 gauge theories with different tree-level superpotentials
Adel Bilal, Steffen Metzger
We consider N=1 supersymmetric U(N) gauge theories with Z_k symmetric tree-level superpotentials W for an adjoint chiral multiplet. We show that (for integer 2N/k) this Z_k symmetr…
Supersymmetric Gauge Theories from String Theory
Steffen Metzger
The subject of this thesis are various ways to construct four-dimensional quantum field theories from string theory. In a first part we study the generation of a supersymmetric Yan…
Special geometry of local Calabi-Yau manifolds and superpotentials from holomorphic matrix models
Adel Bilal, Steffen Metzger
We analyse the (rigid) special geometry of a class of local Calabi-Yau manifolds given by hypersurfaces in C^4 as W'(x)^2+f_0(x)+v^2+w^2+z^2=0, that arise in the study of the large…
M-theory compactifications, G_2-manifolds and anomalies
Steffen Metzger
This diploma thesis has three major objectives. Firstly, we give an elementary introduction to M-theory compactifications, which are obtained from an analysis of its low-energy eff…
Anomaly cancellation in M-theory: a critical review
Adel Bilal, Steffen Metzger
We carefully review the basic examples of anomaly cancellation in M-theory: the 5-brane anomalies and the anomalies on S^1/Z_2. This involves cancellation between quantum anomalies…
Anomalies in M-theory on singular G_2-manifolds
Adel Bilal, Steffen Metzger
When M-theory is compactified on G_2-holonomy manifolds with conical singularities, charged chiral fermions are present and the low-energy four-dimensional theory is potentially an…
