Search for anomalous four-jet events in $e^+ e^-$ annihilation at $\sqrt{s}$ = 130-172 GeV

A study of hadronic events with high jet-multiplicity is performed using the data sample collected by the L3 experiment at LEP at $\sqrt{s}=130-172$ GeV. The observed event rates agree with the Standard Model predictions and upper limits are set on the production cross section of pairs of heavy part...

Sumario:A study of hadronic events with high jet-multiplicity is performed using the data sample collected by the L3 experiment at LEP at $\sqrt{s}=130-172$ GeV. The observed event rates agree with the Standard Model predictions and upper limits are set on the production cross section of pairs of heavy particles that decay hadronically.
