  1. From Hadron Physicsto the Precision FrontierA Very Short Introduction GGSWBS´12 (Tbilisi, August 6 – 10, 2012) August 6, 2012 | Hans Ströher (Forschungszentrum Jülich)

  2. Introduction – Structure of Matter The different layersofmatter constituents

  3. Introduction – Structure of Matter Hadronphysics isthepartof structure-of-matter physics thatdealswith stronglyinteractingparticles atthelevelof quarksandgluons A definitionof „hadronphysics“

  4. Introduction – Standard Model (I) The new „Periodic Table“: matter buildingblocksandforcecarriers

  5. Introduction – Standard Model (II) Last missingpiece: Higgs-boson (mostprobablydiscoveredat CERN)

  6. Introduction – Ordinary Matter Atom Nucleus … iscomprisedofelectronsandu-,d-quarks

  7. Introduction – Ordinary Matter Limited by „radioactivity“ Chemical elements („Periodic Table“)  „Chart of Nuclide“ The diversityofmanifestationsof matter

  8. Introduction – Non-ordinary Matter Cosmic rays … (particles) is (are) produced in energeticcollisions

  9. Introduction – Non-ordinary Matter Cosmic rays 2012 marks100thAnniversaryofCosmic Ray Discovery by Victor Hess

  10. Introduction – Non-ordinary Matter Accelerators … (particles) is (are) produced in energeticcollisions

  11. Hadron Physics – Unsolved Questions No free quarks “Confinement” Mass of hadrons “Mass without mass”  Changes in medium? “Restoration of Chiral Symmetry” Hadronic StatesEnigma of mesons and baryons; resonances; existence of exotics? Force independent of distance QCD vacuum Valence quark Meson Baryon HowdoesNature makeHadrons?

  12. Hadron Physics – Unsolved Questions Hadronic interaction? Remnant of quark- quark interaction Composite nucleon Spin of composite particles (e.g. proton)? “Spin Crisis (Puzzle)” Hadrons in matter Color Transparency, Bound States, … (…) ½ = 3(½)q exotic nuclei HowdoesNature makeHadrons?

  13. Hadron Physics – Unsolved Questions Structure of the nucleon Non- (+,-) symmetric charge distribution? Nucleon charge rests in quarks FromHadronPhysicstothePrecision Frontier

  14. Precision Frontier – New Physics Structure of the nucleon Non- (+,-) symmetric charge distribution? … would have profound implications: d = 0 violates „time-reversal“ symmetry Nucleon charge rests in quarks + - + - Electricdipolemoment(EDM) d

  15. Precision Frontier – EDM Physics Case Big Bang Early Universe MatterAnti-matter Assertion: Universe „started“ withequalamountsof matter and antimatter !

  16. Precision Frontier – EDM Physics Case Big Bang Early Universe MatterAnti-matter Verysoon, a slightasymmetrydeveloped(CP- / T-violation)

  17. Precision Frontier – EDM Physics Case Big Bang Early Universe Matter anti-matter annihilation MatterAnti-matter All theanti-matter annihilatedwith matter

  18. Precision Frontier – EDM Physics Case Big Bang Early Universe Matter anti-matter annihilation Today MatterAnti-matter Now, onlymatterisleftover!  Why do weexistat all?

  19. Precision Frontier – EDM Challenge Nucleon Earth + - 10-15 m A nucleonisverysmall (~ 1 femtometer)

  20. Precision Frontier – EDM Challenge Nucleon Earth expand + - expand dexp < 10-27 [e cm] separation ~ size of a hair 10-15 m An EDM isVEEEEEE … EEERYsmall !!

  21. Precision Frontier – EDMs Status and plans: Neutron EDM Most likely exp. limit for neutron Ongoingsearches: n, e, µ, atoms …  Great physicsbeyond „SM“

  22. Precision Frontier – EDM Approach New: A dedicated precision storage ring for p, d:  Observation of out-of-plane polarization: JEDI Jülich ElectricDipole Moment Investigations Idea: polarizedbeamsinteractingwith E-field  tiltofpolarization

  23. Precision Frontier – EDM Storage Ring Ring concept: 2 counter-rotating beams … A first grade technologicalandscientificchallenge!
