SEARCH FOR NARROW VECTOR RESONANCES IN THE Z MASS RANGE
The hadronic lineshape of the Z has been analysed for evidence of signals of new, narrow vector resonances in the Z-mass range. The production rate of such resonances would be enhanced due to mixing with the Z. No evidence for new states is found, and it is thus possible to exclude, at the 95% confidence level, a quarkonium state in the mass range from 87.7 to 94.7 GeV.
