This review article provides a pedagogical introduction into various classes of chiral string
compactifications to four dimensions with D-branes and fluxes. The main concern is to …

A broad overview of the current status of proton stability in unified models of particle
interactions is given which includes non-supersymmetric unification, SUSY and SUGRA …

▪ Abstract We provide a pedagogical introduction to a recently studied class of
phenomenologically interesting string models known as Intersecting D-Brane Models. The …

This chapter of the report of the “Flavor in the era of the LHC” Workshop discusses the
theoretical, phenomenological and experimental issues related to flavor phenomena in the …

We compute the Yukawa couplings among chiral fields in toroidal Type II compactifications
with wrapping D6-branes intersecting at angles. Those models can yield realistic standard …

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 …

We present a conformal field theory calculation of four-point and three-point correlation
functions for the bosonic twist fields arising at the intersections of D-branes wrapping …

We review particle physics model building in type IIB string theory and F-theory. This is a
region in the landscape where in principle many of the key ingredients required for a …

We present supersymmetric, tadpole-free d= 4, N= 1 orientifold vacua with a three family
chiral fermion spectrum that is identical to that of the standard model. Starting with all simple …

The embedding of the SM hypercharge into an orientifold gauge group is studied. Possible
embeddings are classified, and a systematic construction of bottom–up configurations and …
