  2. Fundamental Symmetries & Cosmic History • What were the fundamental symmetries that governed the microphysics of the early universe? • What insights can precision electroweak studies in nuclear physics provide?

  3. Standard Model puzzles Standard Model successes Fundamental Symmetries & Cosmic History

  4. Present universe Early universe Standard Model High energy desert Weak scale Planck scale Fundamental Symmetries & Cosmic History

  5. Present universe Early universe Standard Model Gravity A “near miss” for grand unification High energy desert Weak scale Planck scale Fundamental Symmetries & Cosmic History

  6. Present universe Early universe Unification Neutrino mass Origin of matter Standard Model Weak scale unstable: Why is GF so large? High energy desert Weak scale Planck scale Fundamental Symmetries & Cosmic History

  7. Cosmic Energy Budget Rotation curves & lensing Cosmic acceleration Stars, planets, Human life Fundamental Symmetries & Cosmic History What is the origin of matter ?

  8. Anthropic Relevance Budget Dark Matter Stars, planets, Human life Dark Energy Baryons Fundamental Symmetries & Cosmic History What is the origin of matter ?

  9. Cosmic Energy Budget Rotation curves & lensing Cosmic acceleration Stars, planets, Human life BBN WMAP SM: 1st order PT and CPV effects too weak Fundamental Symmetries & Cosmic History What is the origin of matter ?

  10. Supersymmetry, GUT’s, extra dimensions… There must have been additional symmetries in the earlier Universe to • Unify all matter, space, & time • Stabilize the weak scale • Produce all the matter that exists • Account for neutrino properties • Give self-consistent quantum gravity

  11. Large Hadron Collider Ultra cold neutrons LANSCE, NIST, SNS CERN What are the new fundamental symmetries? Two frontiers in the search Collider experiments (pp, e+e-, etc) at higher energies (E >> MZ) Indirect searches at lower energies (E < MZ) but high precision Particle, nuclear & atomic physics High energy physics

  12. What are the new fundamental symmetries? • Why is there more matter than antimatter in the present universe? • What are the unseen forces that disappeared from view as the universe cooled? • What are the masses of neutrinos and how have they shaped the evolution of the universe? Electric dipole moment searches Precision electroweak: weak decays, scattering, LFV Neutrino oscillations, 0nbb-decay, q13 , … Tribble report

  13. Present universe Early universe Weak Scale Baryogenesis • B violation • C & CP violation • Nonequilibrium dynamics Sakharov, 1967 Weak scale Planck scale EDMs and Baryogenesis

  14. Weak Scale Baryogenesis • B violation • C & CP violation • Nonequilibrium dynamics Topological transitions Broken phase 1st order phase transition Sakharov, 1967 • Is it viable? • Can experiment constrain it? • How reliably can we compute it? Baryogenesis: New Electroweak Physics Cohen, Kaplan, Nelson Unbroken phase CP Violation
