The significance of the diquark couplings f6QQh and f7ucdchc is studied in a SU(3)× SU(2)×U(1) 1)×U(1)′ gauge model derived from the E6 superstring theory at low energies. For this purpose, the electric dipole moment of the neutron and the branching ratio of the radiative bottom meson decay, B→K*γ, arising from these couplings are claculated. A comparison with the experimental upper limits gives typically the bound Im f6f7≲10−4 for the coupling constants.

B Mixing

The possibilities of B′ meson mixing is discussed. It is found that if fB′ is not much smaller than fπ, B's (or B'd) mixing is possible if |Vt′s Vt′b′/Vcb′| is large, but only for not too heavy b′ masses, e.g. below LEP I energies. The B'b meson will have large mixing for a broad range of parameters; however, it is hard to produce. The vector mesons (B′*) may exhibit mixing phenomena as well. A discussion of our present understanding of meson decay constants of a heavy-light system [Formula: see text] is given. Further efforts on this problem is needed, which will have an impact on our understanding of B mixing as well.
