  A natural solution to the hierachy problem of the standard model is to assume
new physics to appear at the TeV scale. We parametrize the effects of this new
physics in terms of an effective lagrangian and examine its impacts on
electroweak baryogenesis. We point out that with such an effective lagrangian
successful electroweak baryogenesis implies: i) Higgs boson lies within the
reach of LEP II; ii)electric dipole moments of electron and neutron are
detectable in the near future.
