  2. LHC

  3. p p 4 TeV 4 TeV

  4. ??? 126 GeV

  5. - ? excited weakboson spin 0

  6. weakbosons - composite

  7. Standard Model - quarks + leptons weakbosons pointlike

  8. SLAC – DESY LEP - Tevatron radius of electron: radius of u/d-quark:

  34. weakbosons composite

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

  36. - new: H. Fritzsch - arXiv: 1010.1428 - arXiv: 1105.3354 - arXiv: 1203.5600

  37. - masses of composite weak bosons ? analogy

  38. - M QCD

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

  40. - mixing parameter m decay constant

  41. -

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

  43. - QCD +QED mass shift: 3.1 MeV

  44. - ~10.4 GeV
