Query: Dark Matter, Leptogenesis, and Neutrino Mass in the Minimal Extension of
  the SM with $U(1)_{B-L}\otimes Z_{2}$   I suggest a minimal extension of the SM with $U(1)_{B-L}\otimes Z_{2}$. It
can simultaneously accommodate the tiny neutrino mass, cold dark mater and
baryon asymmetry besides the SM. All of the new physics arise from the
$U(1)_{B-L}$ violation at the energy scale about 1000 TeV. The model can
naturally explain the "WIMP Miracle" and elegantly achieve the leptogenesis, in
addition, some predictions of the model are possible and promising to be tested
in near future experiments.
