We analyze electroweak baryogenesis during a two-step electroweak symmetry
breaking transition, wherein the baryon asymmetry is generated during the first
step and preserved during the second. Focusing on the dynamics of CP-violation
required for asymmetry generation, we discuss general considerations for
successful two-step baryogenesis. Using a concrete model realization, we
illustrate in detail the viability of this scenario and the implications for
present and future electric dipole moment (EDM) searches. We find that
CP-violation associated with a partially excluded sector may yield the observed
baryon asymmetry while evading present and future EDM constraints.Comment: 20 pages, 11 figure
