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…
Two Higgs Pair Heterotic Vacua and Flavor-Changing Neutral Currents
Michael Ambroso, Volker Braun, Burt A. Ovrut
We present a vacuum of heterotic M-theory whose observable sector has the MSSM spectrum with the addition of one extra pair of Higgs-Higgs conjugate superfields. The quarks/leptons…
Worldsheet Instantons and Torsion Curves
Volker Braun, Maximilian Kreuzer, Burt A. Ovrut +1
We study aspects of worldsheet instantons relevant to a heterotic standard model. The non-simply connected Calabi-Yau threefold used admits Z_3 x Z_3 Wilson lines, and a more detai…
