  1. Composite Weak Bosons at the LHC Harald Fritzsch LMU Munich

  2. Standard Model two different types of mass generation

  3. mass by confinement QCD

  4. -

  5. masses of weak bosons spontaneous symmetry breaking

  6. Standard Model "Higgs"- boson H H mass => H weak boson

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

  8. - alternative: mass generation of weak bosons confinement

  9. ===> weak bosons composite

  10. - old references: Fritzsch and Mandelbaum (1981) Abbott and Farhi (1981) Fritzsch, Kogerler and Schildknecht (1982) Uehara and Yanagida (1985)

  11. - masses of composite weak bosons ? analogy
