    • There are attempts to generate baryon number asymmetry at the electroweak scale [see, for example, and references therein]. However, it requires a first order phase transition of the electroweak symmetry breaking, and there should be a light Higgs boson (-1.0ex < sim35 GeV) in the minimal standard model [, 46, 282, 550, ] which contradicts the lower bound from LEP (-1.0ex > sim 65 GeV). A large CP violating phase is also necessary in the Higgs potential. Thus at least two doublets of Higgs bosons should be introduced. Moreover, the resulting baryon number asymmetry depends on the details of the dynamics of phase transition, and it is still not clear whether the desired baryon number asymmetry can be generated. Though SUSY predicts two doublets of Higgs bosons, such a large CP violation is difficult to achieve [, N. Maekawa, Phys. Lett. B, 387, ]. Other sources of CP violation in SUSY models are also strongly constrained from the neutron electric dipole [Truncated]

    • Identifying the deficit of the solar neutrino with νe νμ oscillation à la / MSW, we need a Dirac mass simeq 3 GeV for the second generation, which is larger than the charm quark mass.

    • It is quite unnatural to expect that the gauge nonsinglet fields sit precisely on the flat direction from the beginning with a huge value gg MP.
