Hadronic flavor and CP-violating signals of superunification Original Research Article

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, εK/EK, ΔmB, b → sy, the neutron electric dipole moment, dn, 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.
