The D5-brane effective action and superpotential in N=1 compactifications
Thomas W. Grimm, Tae-Won Ha, Albrecht Klemm +1
The four-dimensional effective action for D5-branes in generic compact Calabi-Yau orientifolds is computed by performing a Kaluza-Klein reduction. The N=1 Kaehler potential, the su…
GUTs in Type IIB Orientifold Compactifications
Ralph Blumenhagen, Volker Braun, Thomas W. Grimm +1
We systematically analyse globally consistent SU(5) GUT models on intersecting D7-branes in genuine Calabi-Yau orientifolds with O3- and O7-planes. Beyond the well-known tadpole an…
U(1) Mediation of Flux Supersymmetry Breaking
Thomas W. Grimm, Albrecht Klemm
We study the mediation of supersymmetry breaking triggered by background fluxes in Type II string compactifications with N=1 supersymmetry. The mediation arises due to an U(1) vect…
