Abstract The flavor structure of quarks and leptons and quark-lepton unification are studied in the framework of Pati-Salam models with A 4 modular symmetry. The three generations of the left-handed and right-handed fermions are assigned to be triple

Abstract The formalism of non-holomorphic modular flavor symmetry is developed, and the Yukawa couplings are level N polyharmonic Maaß forms satisfying the Laplacian condition. We find that the integer (even) weight polyharmonic Maaß forms of level

Abstract We analyze a general class of locally supersymmetric, CP and modular invariant models of lepton masses depending on two complex moduli taking values in the vicinity of a fixed point, where the theory enjoys a residual symmetry under a finite

Abstract We have performed a systematical study of the eclectic flavor group ∆(27) ⋊ S 3 which is the extension of the traditional flavor symmetry ∆(27) by the finite modular symmetry S 3. Consistency between ∆(27) and S 3 requires that the e

Abstract We have investigated the modular binary octahedral group 2O as a flavor symmetry to explain the structure of Standard Model. The vector-valued modular forms in all irreducible representations of this group are constructed. We have classified

Abstract The Kähler potentials of modular symmetry models receive unsuppressed contributions which may be controlled by a flavor symmetry, where the combination of the two symmetry types is referred to as eclectic flavor symmetry. After briefly revi

Abstract Texture zeros in fermion mass matrices have been widely considered in tackling the Standard Model flavour puzzle. In this work, we perform a systematic analysis of texture zeros in lepton mass matrices in the framework of Γ 3 ′ ≅ T ′

Abstract We study the systematical one-loop decomposition of the dimension-7 long-range 0νββ decay operators. We find that there are 3 genuine one-loop topologies and 8 diagrams. The procedure to determine the SM quantum number assignments for bot

Abstract We present a neutrino mass model based on modular symmetry with the fewest input parameters to date, which successfully accounts for the 12 lepton masses and mixing parameters through 6 real free parameters including the modulus. The neutrin
