“…[9]). In particular, the symmetry received much attention because it provides a predictive depiction of the mentioned patterns [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. These previous studies are essentially different from the present study in the following basic points:…”

We construct a gauge $B-L$ model with $D_4\times Z_4\times Z_2$ symmetry that can explain the quark and lepton mass hierarchies and their mixings with the realistic CP phases via the type-I seesaw mechanism. Six quark mases, three quark mixing angles and CP phase in the quark sector can get the central values %of Particle Data Group 2022and Yukawa couplings in the quark sector are diluted a range of three orders of magnitude difference by the perturbation theory at the first order.For neutrino sector, the smallness of neutrino mass is achieved by the Type-I seesaw mechanism. Both inverted and normal neutrino mass hierarchies are in consistent with the experimental data. The prediction for the sum of neutrino masses for normaland inverted hierarchies, the effective neutrino masses and the Dirac CP phase are well consistent with all the recent limits.

We present DECO (“Discrete and Efficient Counting of Operators”), an implementation of the Hilbert series to enumerate subleading operator bases for SMEFT-like EFTs with symmetry groups as typically found in flavour and BSM physics. DECO can accommodate EFTs with arbitrary numbers and combinations of the SM gauge groups, as well as the discrete groups S4, A4, and ℤn, and U(1) groups with residual global charge (and these groups’ most important representations). The program is highly modular and can easily be extended to additional groups and/or representations. We demonstrate the design cases for DECO by using it to cross-check subleading operator bases of EFTs in the literature, which allows us to identify a missing operator in a widely used model for the neutrino masses and discuss said operator’s impact.
