Dark Matter, Leptogenesis, and Neutrino Mass in the Minimal Extension of the SM with $U(1{)}_{B-L}\otimes Z_2$

Wei-Min Yang

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 S…
