Geometric Symmetries and Topological Terms in F-theory and Field Theory
Andreas Kapfer
In this thesis we investigate topological aspects and arithmetic structures in quantum field theory and string theory. Particular focus is put on consistent truncations of supergra…
The Arithmetic of Elliptic Fibrations in Gauge Theories on a Circle
Thomas W. Grimm, Andreas Kapfer, Denis Klevers
The geometry of elliptic fibrations translates to the physics of gauge theories in F-theory. We systematically develop the dictionary between arithmetic structures on elliptic curv…
Anomaly Cancelation in Field Theory and F-theory on a Circle
Thomas W. Grimm, Andreas Kapfer
We study the manifestation of local gauge anomalies of four- and six-dimensional field theories in the lower-dimensional Kaluza-Klein theory obtained after circle compactification.…
Partial Supergravity Breaking and the Effective Action of Consistent Truncations
Thomas W. Grimm, Andreas Kapfer, Severin Lust
We study vacua of N = 4 half-maximal gauged supergravity in five dimensions and determine crucial properties of the effective theory around the vacuum. The main focus is on configu…
Self-Dual Tensors and Partial Supersymmetry Breaking in Five Dimensions
Thomas W. Grimm, Andreas Kapfer
We study spontaneous supersymmetry breaking of five-dimensional supergravity theories from sixteen to eight supercharges in Minkowski vacua. This N=4 to N=2 breaking is induced by…
Effective action of 6D F-Theory with U(1) factors: Rational sections make Chern-Simons terms jump
Thomas W. Grimm, Andreas Kapfer, Jan Keitel
We derive the six-dimensional (1,0) effective action arising from F-theory on an elliptically fibered Calabi-Yau threefold with multiple sections. The considered theories admit bot…
