“…For possible choices of CG factors, which relate θ e 12 to the Cabibbo angle θ C , the resulting predictions for θ PMNS 13 have been studied in [18,19]. The specific relation θ PMNS 13 ≈ θ C = ffiffi ffi 2 p , which is close to the measured value, has been discussed recently in the context of GUTs in [21,22]. Fig.…”

We propose new predictions from grand unified theories (GUTs) [applicable to both supersymmetric (SUSY) and non-SUSY models] for the ratios of quark and lepton Yukawa couplings. These new predictions arise from splitting the masses of the messenger fields for the GUT-scale Yukawa operators by Clebsch-Gordan factors from GUT symmetry breaking. This has the effect that these factors enter inversely in the predicted quark-lepton Yukawa coupling ratios, leading to new possible GUT predictions. We systematically construct the new predictions that can be realized in this way in SU(5) GUTs and Pati-Salam unified theories and discuss model building applications.

“…[7][8][9][10][11][12][13][14] The Theory section includes general visions of the physics to be probed at these new facilities, as well as examples of the expected reach in the search for a number of specific models. [15][16][17][18][19][20][21][22][23][24][25] These include the nonunitarity of the leptonic mixing matrix, supersymmetric spectra from Grand Unification Theories. The resonant mono-Higgs production measurements of the Higgs boson potential, and Triple Gauge Coupling measurements are also discussed.…”

“…The simplest GUT gauge symmetry group is SU(5) [59], in which matter fields of standard model are assigned to be5 and 10 dimensional representations. In a generical GUT scheme the down-type quark and charged lepton Yukawa matrices are the crucial factor to produce GUT relations that connect θ 13 with Cabibbo angle, see [60,61]. We remark that a series of models based on discrete flavor symmetry group together with a GUT gauge group have been proposed, for example the SU(5) ×A 4 [62][63][64], SU(5)×S 4 [26,[65][66][67][68][69] and SU(5)×T [70], SO(10)×A 4 [71][72][73], SO(10)×S 4 [74][75][76][77][78][79][80], SO(10)×P SL 2 (7) [81,82] and SO(10)×∆ 27 [83].…”

Abstract:We propose an S 4 flavor model based on supersymmetric (SUSY) SU(5) GUT. The first and third generations of 10 dimensional representations in SU(5) are all assigned to be 1 1 of S 4 . The second generation of 10 is to be 1 2 of S 4 . Right-handed neutrinos of singlet 1 and three generations of5 are all assigned to be 3 1 of S 4 . The VEVs of two sets of flavon fields are allowed a moderate hierarchy, that is Φ ν ∼ λ c Φ e . Tri-Bimaximal (TBM) mixing can be produced at both leading order (LO) and next to next to leading order (NNLO) in neutrino sector. All the masses of up-type quarks are obtained at LO. We also get the bottom-tau unification m τ = m b and the popular Georgi-Jarlskog relation m µ = 3m s as well as a new mass relation m e = 8 27 m d in which the novel Clebsch-Gordan (CG) factor arises from the adjoint field H 24 . The GUT relation leads to a sizable mixing angle θ e 12 ∼ θ c and the correct quark mixing matrix V CKM can also be realised in the model. The resulting CKM-like mixing matrix of charged leptons modifies the vanishing θ ν 13 in TBM mixing to a large θ PMNS 13 θ c / √ 2, in excellent agreement with experimental results. A Dirac CP violation phase φ 12 ±π/2 is required to make the deviation from θ ν 12 small. We also present some phenomenological numerical results predicted by the model.
