Weak Bosons Quarks - Leptons Composite Particles Harald Fritzsch LMU Munich
Standard Model: quarks - leptons - weakbosons ==> pointlike
- 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:
Standard Model two different types ofmassgeneration
- electroweak theory ??? origin of masses of ??? leptons quarks W-bosons ???????????????????????
- alternative: mass generation confinement QCD
weak bosons ? composite

- lefthanded fermions
- haplos simple
- electric charges
- haplons confined by gauge force QHD
- Gauge group of QHD: SU(n) ( e.g. SU(3) )
- massscale of QHD
- QCD 1 GeV
- QCD + QED Dynamical mixing of meson and photon
- decay constant mixing parameter m
- mixing with photon m: mixing parameter ~ 3.1 MeV m = 0.09
- QCD +QED mass shift: 3.1 MeV 1 GeV
- mixing of W with photon m: mixing parameter
- Standard Model
