  The leptogenesis with supersymmetric Higgs triplets is studied in the light
of experimental verification in the TeV region. The lepton number asymmetry
appears just after the inflation via multiscalar coherent evolution of Higgs
triplets and antislepton on a flat manifold. If the Higgs triplet mass terms
dominate over the negative thermal-log term for the Hubble parameter H
comparable to the Higgs triplet mass M_\Delta, the asymmetry is fixed readily
to some significant value by the redshift and rotation of these scalar fields,
providing the sufficient lepton-to-entropy ratio n_L / s \sim 10^-10. This can
be the case even with M_\Delta \sim 1 TeV for the reheating temperature T_R
\sim 10^6 GeV and the mass parameter M / \lambda \sim 10^22 GeV of the
nonrenormalizable superpotential terms relevant for leptogenesis.
