Vanishing Yukawa Couplings and the Geometry of String Theory Models
Lara B. Anderson, James Gray, Magdalena Larfors +1
We provide an overview of recent work which aims to understand patterns of vanishing Yukawa couplings that arise in models of particle physics derived from string theory. These pat…
Generalized Vanishing Theorems for Yukawa Couplings in Heterotic Compactifications
Lara B. Anderson, James Gray, Magdalena Larfors +2
Heterotic compactifications on Calabi-Yau threefolds frequently exhibit textures of vanishing Yukawa couplings in their low energy description. The vanishing of these couplings is…
Almost contact structures on manifolds with a structure
Xenia de la Ossa, Magdalena Larfors, Matthew Magill
We review the construction of almost contact metric (three-) structures, abbreviated ACM(3)S, on manifolds with a structure. These are of interest for certain supersymmetric…
Superpotential of Three Dimensional Heterotic Supergravity
Xenia de la Ossa, Magdalena Larfors, Matthew Magill +1
We dimensionally reduce the ten dimensional heterotic action on spacetimes of the form , where is three dimensional maximally symmetric…
