On Realistic Brane Worlds from Type I Strings
G. Aldazabal, L. Ibanez, F. Quevedo
We review recent progress in constructing realistic brane models from type I string vacua. Explicit models with three families of the standard model gauge group and its left-right…

Non-Perturbative effects from orbifold constructions
G. Aldazabal
We indicate how consistent heterotic orbifold compactifications, including non perturbative information, can be constructed. We first analyse the situation in six dimensions, N=1,…

Standard Grand Unification from Superstrings
Gerardo Aldazabal
Recent developments about the construction of standard and grand unified theories from 4-dimensional superstrings are presented. Explicit techniques involving high…
