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 …

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 present an explicit calculation of the spectrum of a general class of string models,
corresponding to Calabi-Yau flux compactifications with h 1, 2> h 1, 1> 1 with leading …

We propose a bottom-up approach to particle physics model building from string theory. We
start this program by using configurations of type-IIB D3-and D7-branes located at …

We investigate the properties of scalar fields arising from gravity propagating in extra
dimensions. In the scenario of large extra dimensions, proposed by Arkani-Hamed …

D-branes have turned out to be a key ingredient in our present understanding of the
structure of string theory. Interestingly, the fact that D-branes contain gauge fields localized …

A bstract We use string field theory to fix the normalization of the D-instanton corrections to
the superpotential involving the moduli fields of type II string theory compactified on an …

In the presence of internal magnetic fields, a D9 brane can acquire a D5 (or anti-D5) RR
charge, and can therefore contribute to the corresponding tadpole. In the resulting vacua …

Abstract Arkani-Hamed, Dimopoulos, and Dvali have proposed that the fundamental
gravitational scale is close to 1 TeV, and that the observed weakness of gravity at long …
