| Abstract: | Starting point is the hypothesis that the observed Z→e+e?γ decays are mediated by a (composite) spin 0 boson X with 40 mX50 GeV. The consequences for e+e?→e+e?, e+e?→γγ and e+e?→ hadrons at PETRA are explored. PETRA experiments turn out to be sensitive up to masses mX 50 GeV; the best indicator for mX 48 GeV is the angular distribution of Bhabha scattering. |
