Annihilation Radiation of Dark Matter in Heterotic Orbifold Models
G. Bertone, P. Binetruy, Y. Mambrini +1
Direct and indirect dark matter searches can potentially lead to the discovery of Supersymmetry. In the specific context of heterotic orbifold compactification scenarios, it is eve…
Global vs local cosmic strings from pseudo-anomalous U(1)
P. Binetruy, C. Deffayet, P. Peter
We study the structure of cosmic strings produced at the breaking of an anomalous U(1) gauge symmetry present in many superstring compactification models. We show that their coupli…
Fermion mass hierarchies in low energy supergravity and superstring models
P. Binetruy, E. Dudas
We investigate the problem of the fermion mass hierarchy in supergravity models with flat directions of the scalar potential associated with some gauge singlet moduli fields. The l…
Nambu mass hierarchies in strings
P. Binetruy, E. Dudas
We show that a recent proposal by Nambu to generate a hierarchy among Yukawa couplings in the standard model may be easily implemented in superstring models. In such models, two of…
