Fermion masses and flavor mixing in modular A4 symmetry

We consider a flavor model based on the A4 modular group to account for both lepton and
quark parameters (masses and mixing). The inverse seesaw mechanism is considered to produce the
light neutrino masses. Lepton masses and mixing are obtained in terms of Yukawa coupling ratios and
values of the modulus τ nearby some fixed points for inverted neutrino mass hierarchy. The quark masses
and mixing are arisen at the same τ values used in inverted neutrino mass hierarchy and are in agreement
with the recent data.
