- We propose a mechanism called sphalerogenesis to explain the baryon asymmetry of the universe (BAU). The BAU is explained by a CP-violating decay of the electroweak sphaleron. We introduce a dimension-six operator constructed from weak gauge fields: $Q_{\widetilde{W}} \sim Λ^{-2} ε_{ijk} \widetilde{W}_{μν}^{i} W^{j νρ} W_ρ^{kμ}$. We find that the BAU can be explained if $Λ\simeq 38\,{\rm TeV}$. This scenario can be tested by electron electric dipole moment measurements in the near future.
