【 摘 要 】

We study the neutrino mass spectrum in the context of the adjoint SU(5) model constrained by a Z4 flavour symmetry that imposes the nearest-neighbour interaction form on both up- and down-quark mass matrices. We show that at least three adjoint fermionic fields are required in order to reproduce the light neutrino mass spectrum.
