Baryogenesis and EDMs Theoretical Tasks

• Attaining reliable computations that relate
  particle physics models of new CP-violation to
  EDMs of complex systems (neutron, atoms, nuclei)
• Attaining reliable computations of the baryon
  asymmetry from fundamental particle physics
  theories with new CP-violation

Nonperturbative QCD, atomic nuclear structure

• Non-equilibrium quantum transport
• Non-zero T and m
• Spacetime dynamics of cosmic phase transitions

Summary Outlook

• EWB remains a viable option for explaining the
  cosmic baryon asymmetry that can be tested and
  constrained using EDMs, precision electroweak,
  and collider input
• New developments using non-equilibrium QFT are
  putting YB computations on a more systematic
  footing that will allow for detailed
  confrontations with lab experiments
• Considerable (hard) work remains to be completed
• Exciting field involving an interplay between
  cosmology and particle/nuclear physics in both
  theory and experiment

Complete set of transport coefficients, refined
studies of bubble dynamics, applications to
various scenarios for new CP-violation,
phenomenology (EDM, Dark Matter, B physics,
precision electroweak, collider)
