Query: Electroweak Baryogenesis: An Overview (Where are We Now?)   It now seems plausible that the observed baryon asymmetry may have been
produced at the electroweak phase transition. We review the considerations
which lead to this conclusion, focusing on the obstacles to making reliable
estimates. These arise from incomplete knowledge of baryon-violating rates near
the phase transition, our limited understanding of the phase transition itself,
and incomplete understanding of the mechanisms which actually lead to an
asymmetry.
