Abstract

During the LEP run at root s = 130 - 140 GeV the ALEPH Collaboration reported a significant excess in the rate of four-jet production and a structure in the invariant mass spectrum. This structure was confirmed by ALEPH during the other two runs of LEP at root s = 161 and 172 GeV. The other three LEP experiments did not find any significant evidence for the same signal. A LEP working group was convened to study the subject. The main results of this work are reported and discussed in this paper.
