             Summary


•   EWB remains a viable and testable
    scenario for explaining the cosmic
    baryon asymmetry
•   We are making progress in refining YB
    & EDM computations with reduced
    theoretical uncertainties
•   Input from EDM searches, collider
    studies, & theory needed to address
    the origin of matter problem
