  1. Composite Weak Bosons LHC

  2. CERN LHC

  3. ATLAS at Large Hadron Collider / CERN

  4. CMS

  5. Standard Model: quarks - leptons - weak bosons ==> pointlike

  6. present limit on the substructure of leptons and quarks

  7. - mass Problem for Standard Model

  8. Mass: - 1686

  9. - mass 1916 geometry ( General Relativity )

  10. - mass universal

  11. Standard Model two different types of mass generation

  12. mass by confinement QCD

  13. electroweaktheory spontaneous symmetry breaking

  14. proton weak boson ? <=mass=> H H

  15. - alternative: mass generation confinement

  16. ===> weak bosons composite

  17. v = 246 GeV => 0.3 TeV !! new interaction !!

  18. - old references: Bjorken (1977) Fritzsch and Mandelbaum (1981) Abbott and Farhi (1981) Barbieri and Mohapatra (1981) Fritzsch, Kogerler and Schildknecht (1982) Uehara and Yanagida (1985)

  19. - new: Fritzsch (2010) arXiv:1010.1428

  20. - masses of composite weak bosons ? analogy

  21. - QCD quark masses = 0 no electromagnetism

  22. - QCD + QED Dynamical mixing of rho meson and photon:

  23. - mixing parameter m decay constant

  24. -

  25. - m: mixing parameter m = 0.09

  26. - mixing mass shift: 3.1 MeV

  27. - masses of composite weak bosons ?

  28. W ====>>> constituents

  29. - lefthanded fermions

  30. -

  31. - electric charges

  32. -

  33. - haplons confined by gauge force QHD

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

  35. - mass scale of Q H D

  36. - QHD Dynamical mixing of W-boson and photon

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

  38. - Standard Model

  39. -

  40. - Q C D

  41. - Q H D

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

  43. - W decay constant
