Open strings
C Angelantonj, A Sagnotti - Physics reports, 2002 - Elsevier
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 …

Noncommutative compactifications of type I strings on tori with magnetic background flux
R Blumenhagen, L Goerlich, B Körs… - Journal of High Energy …, 2000 - iopscience.iop.org
We construct six-and four-dimensional toroidal compactifications of the type-I string with
magnetic flux on the D-branes. The open strings in this background probe a …

Bent domain walls as braneworlds
N Kaloper - Physical Review D, 1999 - APS

Brane supersymmetry breaking
I Antoniadis, E Dudas, A Sagnotti - Physics Letters B, 1999 - Elsevier
We show how to construct chiral tachyon-free perturbative orientifold models, where
supersymmetry is broken at the string scale on a collection of branes while, to lowest order …

Supersymmetry and electroweak breaking from extra dimensions at the TeV scale
A Delgado, A Pomarol, M Quiros - Physical Review D, 1999 - APS
We analyze some features of the role that extra dimensions, of radius R in the TeV− 1 range,
can play in the soft breaking of supersymmetry and the spontaneous breaking of …

Comments on open-string orbifolds with a non-vanishing Bab
C Angelantonj - Nuclear Physics B, 2000 - Elsevier
We study the effect of a non-vanishing flux for the NS–NS antisymmetric tensor in open-
string orbifolds. As in toroidal models, the total dimension of the Chan–Paton gauge group is …
