Box Graphs and Resolutions II: From Coulomb Phases to Fiber Faces
Andreas P. Braun, Sakura Schafer-Nameki
Box graphs, or equivalently Coulomb phases of three-dimensional N=2 supersymmetric gauge theories with matter, give a succinct, comprehensive and elegant characterization of crepan…
Froggatt-Nielsen meets Mordell-Weil: A Phenomenological Survey of Global F-theory GUTs with U(1)s
Sven Krippendorf, Sakura Schafer-Nameki, Jin-Mann Wong
In F-theory, U(1) gauge symmetries are encoded in rational sections, which generate the Mordell-Weil group of the elliptic fibration of the compactification space. Recently the pos…
F-theory and All Things Rational: Surveying U(1) Symmetries with Rational Sections
Craig Lawrie, Sakura Schafer-Nameki, Jin-Mann Wong
We study elliptic fibrations for F-theory compactifications realizing 4d and 6d supersymmetric gauge theories with abelian gauge factors. In the fibration these U(1) symmetries are…
