Type I Vacua from Diagonal -Orbifolds

Gianfranco Pradisi

We discuss the open descendants of diagonal irrational orbifolds, starting from the case and analyzing six-dimensional and four-dimensional models. As recently argued,…

Fivebrane instantons and higher derivative couplings in type I theory

Amine B. Hammou, Jose F. Morales

We express the infinite sum of D-fivebrane instanton corrections to couplings in type I string vacua, in terms of an elliptic index counting 1/2-BPS excit…

D-branes on Fourfolds with Discrete Torsion

Subir Mukhopadhyay, Koushik Ray

We study D1-branes on the fourfold $\C^4/(\Z_2\times\Z_2\times\Z_2)$, in the presence of discrete torsion. Discrete torsion is incorporated in the gauge theory of the D1-branes by…

Discrete torsion in non-geometric orbifolds and their open-string descendants

Massimo Bianchi, Jose' F. Morales, Gianfranco Pradisi

We discuss some Z_N^L x Z_N^R orbifold compactifications of the type IIB superstring to D= 4,6 dimensions and their type I descendants. Although the Z_N^L x Z_N^R generators act as…

Brane Supersymmetry Breaking

I. Antoniadis, E. Dudas, A. Sagnotti

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, th…

Open Descendants of Z_2\times Z_2 Freely-Acting Orbifolds

I. Antoniadis, G. D'Appollonio, E. Dudas +1

We discuss Z_2 \times Z_2 orientifolds where the orbifold twists are accompanied by shifts on momentum or winding lattice states. The models contain variable numbers of D5 branes,…

Candidates for anti-de Sitter Horizons

Koushik Ray

We find, from the toric description of the moduli space of D3-branes on non-compact six-dimensional singularities $\C^3/\Z_3$ and $\C^3/\Z_5$ in the blown-down limit, the four-dime…

On the perturbative corrections around D-string instantons

E. Gava, A. Hammou, J. F. Morales +1

We study -threshold corrections in an eight dimensional S-dual pair of string theories, as a prototype of dual string vacua with sixteen supercharges. We show that the…
