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 review is devoted to open strings, and in particular to the often surprising features of
their spectra. It follows and summarizes developments that took place mainly at the …

We study the spectrum of open strings on AdS2 branes in AdS3 in an NS–NS background,
using the SL (2, R) WZW model. When the brane carries no fundamental string charge, the …

We present what we believe are the first specific string (D-brane) constructions whose low-
energy limit yields just a three generation SU (3)× SU (2)× U (1) standard model with no …

We compute Yukawa couplings involving chiral matter fields in toroidal compactifications of
higher dimensional super-Yang-Mills theory with magnetic fluxes. Specifically we focus on …

We review the particle theory origin of inflation and curvaton mechanisms for generating
large scale structures and the observed temperature anisotropy in the cosmic microwave …

We construct the first three family N= 1 supersymmetric string model with standard model
gauge group SU (3) C× SU (2) L× U (1) Y from an orientifold of type IIA theory on T 6/(Z 2× Z …

We systematically investigate instanton corrections from wrapped Euclidean D-branes to the
matter field superpotential of various classes of N= 1 supersymmetric D-brane models in four …
