Abstract

I suggest a minimal extension of the SM with U(1)_B-L⊗ Z₂. 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.
