Abstract
The flavor changing and CP-violating phenomena predicted in supersymmetric unified theories as a consequence of the large top quark Yukawa coupling, are investigated in the quark sector and compared with related phenomena in the lepton sector, considered previously. In particular we study εK, ε K / E K , Δm B , b → sy, the neutron electric dipole moment, d n , and CP violation in neutral B meson decays, both in minimal SU(5) and SO(10) theories. The leptonic signals are generically shown to provide more significant tests of quark-lepton unification. Nevertheless, mostly in the SO(10) case, a variety of hadronic signals is also possible, with interesting correlations among them.
