Neutrino Masses with a Suitable Parametrization in the PPF 3-3-1 Gauge   Model
  Plausible phenomenological consequences of the well-known Pisano-Pleitez- Frampton 3-3-1 model - such as the neutrino masses - are analyzed within the solution provided by the exact algebraical approach - proposed several years ago by Cotaescu - for gauge models with high symmetries. We prove that a suitable parametrisation in the Higgs sector and a redefinition of the three scalar triplets involved therein can lead to realistic predictions for the lepton mass spectrum, while a minimal number of coupling parameters are employed in the Yukawa sector.
