Moduli stabilization in (string) model building: gauge fluxes and loops
A. P. Braun, A. Hebecker, M. Trapletti
We discuss the moduli stabilization arising in the presence of gauge fluxes, R-symmetry twists and non-perturbative effects in the context of 6-dimensional supergravity models. We…
Toric Resolutions of Heterotic Orbifolds
Stefan Groot Nibbelink, Tae-Won Ha, Michele Trapletti
We investigate resolutions of heterotic orbifolds using toric geometry. Our starting point is provided by the recently constructed heterotic models on explicit blowup of C^n/Z_n si…
Multiple anomalous U(1)s in heterotic blow-ups
S. Groot Nibbelink, H. P. Nilles, M. Trapletti
The existence of multiple anomalous U(1)s is demonstrated explicitly in a blow-up version of a heterotic Z_3 orbifold. Another blow-up of the same orbifold supports further evidenc…
Open string models with Scherk-Schwarz SUSY breaking
M. Trapletti
We apply the well-known Scherk-Schwarz supersymmetry breaking mechanism in an open string context. We construct a new Z_3\times Z_3^\prime model, containing only D9-branes, and red…
