Revisiting the Dirac Nature of Neutrinos

Amid the uncertainty regarding the fundamental nature of neutrinos, we adhere to the Dirac one, and construct a model in the light of Δ(27) symmetry. The model is enriched by an additional Z₁₀ symmetry, to eliminate the possibility of the Majorana mass terms. The neutrino mass matrix exhibits four texture zeroes, and the associated mixing scheme aligns with the experimental data, notably controlled by a single parameter. In addition, the model emphasizes on the standard parametrization of the lepton mixing matrix, which is crucial in the light of model building and neutrino physics experiments
