Query: An SU(5) grand unified model with discrete flavour symmetries   We propose a model based on the $SU(5)$ grand unification with an extra
$Z_{2}\otimes Z_{2}^{\prime}\otimes Z_{2}^{\prime \prime}\otimes Z_{4}\otimes
Z_{12}$ flavor symmetry, which successfully describes the observed SM fermion
mass and mixing pattern. The observed quark mass and mixing pattern is caused
by the $Z_{4}$ and $Z_{12}$ symmetries, which are broken at very high scale by
the $SU(5)$ scalar singlets $\sigma $ and $\chi $, charged respectively under
these symmetries and which acquire VEVs at the GUT scale. The light neutrino
masses are generated via a type I seesaw mechanism with three heavy Majorana
neutrinos. The model has in total 17 effective free parameters, from which 2
are fixed and 15 are fitted to reproduce the experimental values of the 18
physical parameters in the quark and lepton sectors. The model predictions for
both quark and lepton sectors are in excellent agreement with the experimental
data.
