Lorentz spinors in elastic WW scattering and neutral currents

  • E. H. Lemke


We propose a novel electroweak unification scheme that can be interpreted in terms of compositeness and an effective Lagrangian and show that it leads to a good high-energy behaviour of the reactions WW→WW, νν→WW and ee→WW. The weak vector bosons are no more gauge fields. The description of the reactions WLWL→WLWL and WTWL→WLWL becomes simpler than in the non-Abelian case: no seagull term is necessary and no scalar boson must be exchanged to get a good high-energy behaviour. We obtain a low-energy neutral current phenomenology that is identical with the usual one. The LEP II process ee→WW is analysed in some detail. The relative sign of the individual amplitudes can be determined. We find clear Lorentz spinor signals. They would be indicative of the existence of a Z′-boson as well as a heavy neutrino (N). The upper unitarity mass boundmN<890 GeV is derived.
