  1. QCD 1972 Fritzsch # Gell-Mann

  2. 2012:QCD 40 yearsconference in Oberwoelz, Austrian Alpsfritzsch@mppmu.mpg.de

  3. Salzburg Vienna Alps Oberwoelz 80 km Graz Klagenfurt

  4. fritzsch@mppmu.mpg.de

  5. Weak Bosons Quarks - Leptons Composite Particles Harald Fritzsch LMU Munich

  6. Standard Model: quarks - leptons - weakbosons ==> pointlike

  7. - l i m i t s f r o m e x p e r i m e n t : radius of electron: radius of u/d-quark:

  8. Standard Model two different types ofmassgeneration

  9. mass by confinement QCD

  10. protonmassfieldenergyofgluonsandquarks

  11. -

  12. - electroweak theory ??? origin of masses of ??? leptons quarks W-bosons ???????????????????????

  13. ????????????? „Higgs“ mechanism??????????

  14. - alternative: mass generation confinement QCD

  15. weak bosons ? composite

  16. - old references: Bjorken (1977) Fritzsch and Mandelbaum (1981) Abbott andFarhi (1981) Barbieri andMohapatra (1981) Fritzsch, Kogerlerand Schildknecht (1982) Lüst (1985) Calmetand Fritzsch (2000)

  17. - new: H. Fritzsch - arXiv: 1010.1428 - arXiv: 1105.3354

  18. rho – mesonsgauge bosons( Sakurai …)quark- antiquarkbound states(QCD)

  19. weak bosons gauge bosons- SU(2) x U(1) -? bound states ?

  20. - analogy

  21. W ====>>> constituents

  22. - lefthanded fermions

  23. - haplos simple

  24. - electric charges

  25. -

  26. - haplons confined by gauge force QHD

  27. - Gauge group of QHD: SU(n) ( e.g. SU(3) )

  28. - massscale of QHD

  29. - QCD 1 GeV

  30. - QCD + QED Dynamical mixing of meson and photon

  31. - decay constant mixing parameter m

  32. -

  33. - mixing with photon m: mixing parameter ~ 3.1 MeV m = 0.09

  34. - QCD +QED mass shift: 3.1 MeV 1 GeV

  35. - mixing of W with photon m: mixing parameter

  36. - Standard Model

  37. - Standard Model ~10.4 GeV

  38. - QCD + QED QHD+ QED ~10.4 GeV ~3.1 MeV

  39. - W decay constant
