Modular invariant dynamics and fermion mass hierarchies around τ = i
Abstract We discuss fermion mass hierarchies within modular invariant flavour models. We analyse the neighbourhood of the self-dual point τ = i, where modular invariant theories possess a residual Z 4 invariance. In this region the breaking of Z 4 can be fully described by the spurion ϵ ≈ τ − i, tha...
