Query: Late Leptogenesis from Radiative Soft Terms   We point out that the so-called ``soft leptogenesis'' can occur at TeV scale
if the $B$ term is generated through radiative corrections which involve
two-loop diagrams with the gaugino exchange. This mechasnism requires the
non-trivial CP phase, ${Im}(A m_{1/2}^*)\neq 0$, and can naturally explain the
observed baryon asymmetry of the universe associated with the TeV scale seesaw
mechanism. Such a low scale leptogenesis would be a promising option in view of
the tight upper limit on the reheat temperature avoiding the gravitino problem
in supergravity models.
