Leptogenesis and Dark Matter related ?
Nicolas Cosme, Laura Lopez Honorez, Michel H. G. Tytgat
We investigate the possibility that dark matter and the baryon asymmetry of the Universe are generated by the same mechanism, following an idea initially proposed by V.A. Kuzmin an…
Gauge dilution in leptogenesis
N. Cosme
We discuss leptogenesis in its natural context, i.e. gauge unification, by including in the analysis the effects of the gauge sector associated to the Majorana neutrinos. It result…
Leptogenesis, neutrino masses and gauge unification
N. Cosme
Leptogenesis is considered in its natural context where Majorana neutrinos fit in a gauge unification scheme and therefore couple to some extra gauge bosons. The masses of some of…
CP violation in weak interactions from orbifold reduction: possible unification structures
N. Cosme, J. -M. Frere
We present a mechanism to generate complex phases from real 4+1 dimensional couplings in a model of weak interactions through dimensional reduction of a gauge theory. The orbifoldi…
CP violation from dimensional reduction: a simple example
N. Cosme
CP is a symmetry of pure gauge theories, that is without scalar interactions. Actually its violation originates in the Standard Model from the completely arbitrary Yukawa couplings…
CP Violation from Dimensional Reduction: Examples in 4+1 Dimensions
N. Cosme, J. -M. Frere, L. Lopez Honorez
We provide simple examples of the generation of complex mass terms and hence CP violation through dimensional reduction.
