Some issues in soft SUSY-breaking terms from dilaton/moduli sectors
A. Brignole, L. E. Ibanez, C. Munoz +1
We study the structure of the soft SUSY-breaking terms obtained from some classes of 4-D strings under the assumption of dilaton/moduli dominance in the process of SUSY-breaking. W…
Neutrino Masses from Gauge Symmetries
H. Dreiner, G. K. Leontaris, S. Lola +2
A very simple extension of the standard model to include an Abelian family symmetry is able to describe the hierarchy of quark and lepton masses and their mixing angles together wi…
Constraints on discrete symmetries from anomaly cancellation in compactified superstring theories
Graham G. Ross, Christoph M. A. Scheich
Compactified string theories give rise to discrete symmetries which are essential if they are to provide a realistic low energy theory. We find that in a class of four dimensional…
More about discrete symmetries in compactified string theories
Christoph M. A. Scheich
We discuss discrete symmetries in several string compactification schemes. The same constraints on the light spectra as for Gepner models \cite{rosss} are found in various cases fo…
