Non-holomorphic modular S 4 lepton flavour models

Abstract In the formalism of the non-supersymmetric modular invariance approach to the flavour problem the elements of the Yukawa coupling and fermion mass matrices are expressed in terms of polyharmonic Maaß modular forms of level N in addition to the standard modula forms of the same level and a s...
