Towards a complete A4 × SU(5) SUSY GUT

Abstract: Abstract:We propose a renormalisable model based on A 4 family symmetry with an SU(5) grand unified theory (GUT) which leads to the minimal supersymmetric standard model (MSSM) with a two right-handed neutrino seesaw mechanism. Discrete Z 9 × Z 6 symmetry provides the fermion mass hierarchy in both the quark and lepton sectors, while Z R 4 symmetry is broken to Z R 2 , identified as usual R-parity. Proton decay is highly suppressed by these symmetries. The strong CP problem is solved in a similar way to the Ne… Show more

“…Even such a minimal SU(5) GUT group requires a whole sector to break the gauge symmetry to the SM and to achieve the doublet-triplet Higgs splitting of the light electroweak doublet from the heavy colour triplet [20,21]. However many of the complications of doublet-triplet splitting are avoided by assuming the existence of extra dimensions [22][23][24].…”

“…The seesaw mechanism [7][8][9][10][11][12] leads to a light effective Majorana neutrino mass matrix: m a = |a| 2 /M atm and m b = |b| 2 /M sol may be taken to be real and positive without loss of generality, the physical predictions only depending on a relative phase whose phenomenologically preferred value is η = 2π/3 [18]. Following the proposed lepton model in [18], this structure has been incorporated into unified models of quarks and leptons in [19,20]. It has also been shown to lead to successful leptogenesis in which not only the sign of baryon asymmetry is determined by the ordering of the heavy right-handed neutrinos, but also η is identified as the leptogenesis phase, directly linking CP violation in the laboratory with that in the early universe [21].…”

“…1 It is remarkable that, with µ 1,2 fitted to the neutrino masses, the entire PMNS matrix is then uniquely determined with no free parameters, giving predictions for mixing angles and the CP phase in agreement with current data. In order to extend the above ideas into a unified model of flavour, the CSD3 model with two RH neutrinos may be embedded into an A 4 × SU(5) Grand Unified Theory (GUT) [32,33]. However, from a theoretical point of view, the SO(10) GUT is preferred, since it predicts three RH neutrinos and makes neutrino mass inevitable.…”
