Neutrino Majorana Masses from String Theory Instanton Effects
L. E. Ibanez, A. M. Uranga
Finding a plausible origin for right-handed neutrino Majorana masses in semirealistic compactifications of string theory remains one of the most difficult problems in string phenom…
Coisotropic D8-branes and Model-building
A. Font, L. E. Ibanez, F. Marchesano
Up to now chiral type IIA vacua have been mostly based on intersecting D6-branes wrapping special Lagrangian 3-cycles on a CY three-fold. We argue that there are additional BPS D-b…
Flux-Induced Baryon Asymmetry
L. E. Ibanez
I propose that the primordial baryon asymmetry of the universe was induced by the presence of a non-vanishing antisymmetric field background H_ijk across the three space dimensions…
More Dual Fluxes and Moduli Fixing
G. Aldazabal, P. G. Camara, A. Font +1
We generalize the recent proposal that invariance under T-duality leads to additional non-geometric fluxes required so that superpotentials in type IIA and type IIB orientifolds ma…
