Composite W-bosons Harald Fritzsch LMU Munich
Standard Model 2 different types of mass generation
a) dynamical ( proton mass, rho meson mass …) b) via scalar fields ( W-masses … )
Nucleon Mass in limit of vanishing quark masses: const. calculable in QCD Mass: confined field energy
1 / dimensional transmutation
: 250 MeV Experiments
- masses of weak bosons, leptons and quarks?
- Principle: The masses of all particles are due to dimensional transmutation.
- weak bosons composite
Rho Meson - q q
- new gauge theory: hypercolor interaction QHD
- mass scale of hypercolor interaction
- Haplon Model Fritzsch and Mandelbaum Fritzsch, Kogerler and Schildknecht
radius: 0.000 000 000 000 000 010 cm W
- Gauge group of hypercolor: SU(n) Example: SU(3)
- QCD----------------QHD SU(3,c)----------SU(3,h)
QCD - QHD mesons, baryons weak bosons, leptons, quarks
large distance: linear potential in QCD and QHD QCD - q q - h QHD h

- Electric charges
- W+ W- W(0)
- fermions scalars
- electric charges:
- red quarks
- QCD
- QHD: W-mass
mass scale of hypercolor interaction?
- Dynamical mixing of rho meson and photon in QCD: photon rho
- mixing parameter m:
- Dynamical mixing of W-boson and photon: photon W
- Mixing of neutral W and photon: mixing parameter m
- standard model:
- QCD QHD
QCD QHD energy scale: about 1000 times larger
- new bound states below 1 TeV
- expected: isoscalar boson M(S) larger than 0.5 TeV
- ~ ~ W, Z W, Z 0.4 TeV

- quark – quark scattering at the LHC scalar q q fermion
- comparison:
- One event of one million events should display the substructure
