Global F-theory GUTs
Ralph Blumenhagen, Thomas W. Grimm, Benjamin Jurke +1
We construct global F-theory GUT models on del Pezzo surfaces in compact Calabi-Yau fourfolds realized as complete intersections of two hypersurface constraints. The intersections…
SUSY Breaking in Local String/F-Theory Models
R. Blumenhagen, J. P. Conlon, S. Krippendorf +2
We investigate bulk moduli stabilisation and supersymmetry breaking in local string/F-theory models where the Standard Model is supported on a del Pezzo surface or singularity. Com…
F-theory uplifts and GUTs
Ralph Blumenhagen, Thomas W. Grimm, Benjamin Jurke +1
We study the F-theory uplift of Type IIB orientifold models on compact Calabi-Yau threefolds containing divisors which are del Pezzo surfaces. We consider two examples defined via…
D-brane Instantons in Type II String Theory
Ralph Blumenhagen, Mirjam Cvetic, Shamit Kachru +1
We review recent progress in determining the effects of D-brane instantons in N=1 supersymmetric compactifications of Type II string theory to four dimensions. We describe the abst…
