"A detailed study of four-jet hadronic events at LEP 1.5 has been reported by the ALEPH collaboration. From selected four-jet events, the invariant masses of jet pairs are computed, and out of the three jet combinations, the one with the lowest difference in jet-pair masses is retained. [...] Not only is the total number of four-jet events observed by ALEPH at 130-140 GeV larger than expected from QCD, but this excess is contained in a narrow window around 105 GeV for the sum of jet-pair masses. In this window, about two times the width of the estimated resolution, nine events are observed with only 0.8 events expected from QCD."
