2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/112516We study stabilization of moduli in the type--IIB superstring theory on the six-dimensional toroidal orientifold $\T^6/Ω\cdot(-1)^{F_L}\cdot\Z_2$. We consider background space-filling D9-branes wrapped on the orientifold along with non-Abelian fluxes on its world-volume and demonstrate with two examples that this can stabilize all the complex structure moduli and some of the Kähler moduli.18 pages, LaTeX, references addedHigh Energy Physics - Theorytext
