Nonabelian Discrete Symmetries, Fermion Mass Textures and Large Neutrino Mixing
Paul H. Frampton, Andrija Rasin
Nonabelian discrete groups are an attractive tool to describe fermion masses and mixings. They have nonsinglet representations which seem particularly suitable for distinguishing t…
Intermediate Scales in Supersymmetric GUTs: the Survival of the Fittest
Charanjit S. Aulakh, Borut Bajc, Alejandra Melfo +2
We show that intermediate scales in supersymmetric grand unified theories may exist naturally. Their origin is traced to the violation of the survival principle: in supersymmetry i…
See-saw and Supersymmetry or Exact R-parity
Charanjit S. Aulakh, Alejandra Melfo, Andrija Rasin +1
We show how the renormalizable see-saw mechanism in the context of supersymmetry and spontaneously broken B-L symmetry implies exact R-parity at all energies. We argue that supersy…
Unification with Enlarged Kaluza-Klein Dimensions
Paul H. Frampton, Andrija Rasin
In minimal theories with extra spatial dimensions at scales mu_0 much lower than the conventional GUT scale, unification can give too-large predictions for alpha_3(M_Z) given alpha…
