• D-brane compactifications
• GUT's
• D-instantons

This proceeding is based on the paper 1010.5188 [hep-th] where we discuss SU(5) Grand Unified Theories in the context of orientifold compactifications. Specifically, we investigate three D-brane stack realizations of the Georgi-Glashow model and analyze them with respect to their Yukawa couplings. We show that most/all phenomenological problems that appear in two stack models can be resolved in three stack models. We exemplify with globally consistent Georgi-Glashow models based on RCFT that these D-brane quivers can be indeed embedded in a global setting.
