Query: Predictive SUSY GUT Model for CP Violation, Fermion Masses and Mixings   CP violation, fermion masses and mixing angles including that of neutrinos
are studied in an SUSY SO(10)$\times \Delta (48)\times$ U(1) model. The
nonabelian SU(3) discrete family symmetry $\Delta(48)$ associated with a simple
scheme of U(1) charge assignment on various fields concerned in superpotential
leads to unique Yukawa coupling matrices with zero textures. Thirteen
parameters involving masses and mixing angles in the quark and charged lepton
sector are successfully predicted by only four parameters. The masses and
mixing angles for the neutrino sector could also be predicted by constructing
an appropriate heavy Majorana neutrino mass matrix without involving new
parameters. It is found that the atmospheric neutrino deficit, the mass limit
put by hot dark matter and the LSND $\bar{\nu}_{\mu} \to \bar{\nu}_{e}$ events
may simultaneously be explained, but solar neutrino puzzle can be solved only
by introducing a sterile neutrino. An additional parameter is added to obtain
the mass and mixing of the sterile neutrino. The hadronic parameters $B_{K}$
and $f_{B}\sqrt{B}$ are extracted from the observed $K^{0}$-$\bar{K}^{0}$ and
$B^{0}$-$\bar{B}^{0}$ mixings respectively. The direct CP violation
($\epsilon'/\epsilon$) in kaon decays and the three angles $\alpha$, $\beta$
and $\gamma$ of the unitarity triangle in the CKM matrix are also presented.
More precise measurements of $\alpha_{s}(M_{Z})$, $|V_{cb}|$,
$|V_{ub}/V_{cb}|$, $m_{t}$, as well as various CP violation and neutrino
oscillation experiments will provide an important test for the present model
and guide us to a more fundamental theory.
