LGRT 419B

Explaining the cosmic matter-antimatter asymmetry requires CP-violation beyond that of the Standard Model. Electric dipole moment searches and measurements of CP-violating observables in heavy quark systems place tight constraints on new CP-violation at and below the weak scale. Next generation EDM searches and heavy flavor probes, together with prospective collider tests, will have considerably greater sensitivities. This workshop will explore how these future probes of CP-violation may provide tests of scenarios proposed to explain the matter-antimatter asymmetry. Specific questions to be addressed include:

* What are the viable baryogenesis scenarios that could lead to CP-violating signatures in next generation experiments?

* In what ways can high-energy collider, heavy flavork and EDM searches provide complementary probes?
