TL;DR: In this paper, a review article provides a pedagogical introduction to various classes of chiral string compactifications to four dimensions with D-branes and fluxes with the main concern being to provide all necessary technical tools to explicitly construct four-dimensional orientifold vacua, with the final aim to come as close as possible to the supersymmetric standard model.

TL;DR: In this paper, a pedagogical introduction to a recently studied class of phenomenologically interesting string models known as Intersecting D-Brane Models is provided, where the gauge fields of the Standard Model are localized on D-branes wrapping certain compact cycles on an underlying geometry, whose intersections can give rise to chiral fermions.

TL;DR: In this paper, the authors systematically investigate instanton corrections from Euclidean D-branes to the matter field superpotential of various classes of N = 1 supersymmetric Dbrane models in four dimensions.

TL;DR: In this article, the authors constructed six-and four-dimensional toroidal compactifications of the Type I string with magnetic flux on the D-branes and investigated the spectra of such non-commutative string compactifications.

TL;DR: In this paper, the perturbative stability of non-supersymmetric intersecting brane world models on tori is analyzed and the phenomenological implications of a three generation Standard Model which descends naturally from an SU (5) GUT theory.
