Is leptogenesis falsifiable at LHC?
J. -M. Frère, T. Hambye, G. Vertongen
It is well known that the leptogenesis mechanism offers an attractive possibility to explain the baryon asymmetry of the universe. Its particular robustness however comes with one…
About Mass, CP and Extra Dimensions
J. -M. Frère
We discuss the notion of mass, mostly for fermions, and its relation to the breaking of CP invariance, the natural symmetry of gauge interactions. In a first model, we show how com…
Searching for family-number conserving neutral gauge bosons from extra dimensions
J. M. Frere, M. V. Libanov, E. Ya. Nugaev +1
Previous studies have shown how the three generations of the Standard Model fermions can arise from a single generation in more than four dimensions, and how off-diagonal neutral c…
Neutrino Mass Patterns within the See-saw Model from Multi-localization along Extra Dimensions
J. -M. Frere, G. Moreau, E. Nezri
We study a multi-localization model for charged leptons and neutrinos, including the possibility of a see-saw mechanism. This framework offers the opportunity to allow for realisti…
Flavour violation with a single generation
J. -M. Frere, M. V. Libanov, E. Ya. Nugaev +1
We calculate probabilities of flavour violating processes mediated by Kalutza-Klein modes of gauge bosons in a model where three generations of the Standard Model fermions arise fr…
Gaugino-induced quark and lepton masses in a truly minimal left-right model
J. -M. Frere, Ernest Ma
It has recently been proposed that all fundamental fermion masses (whether Dirac or Majorana) come from effective dimension-five operators in the context of a truly minimal left-ri…
