Four-jet final state production in $e^{+}e^{-}$ collisions at centre-of-mass energies of 130 and 136 GeV

Mostrar otras versiones (1)

The four-jet final state is analyzed to search for hadronic decays of pair-produced heavy particles. The analysis uses the ALEPH data collected at LEP in November 1995 at centre-ofmass energies of 130 and 136 GeV, corresponding to a total integrated luminosity of 5.7 pb-1. An excess of four-jet even...

description The four-jet final state is analyzed to search for hadronic decays of pair-produced heavy particles. The analysis uses the ALEPH data collected at LEP in November 1995 at centre-ofmass energies of 130 and 136 GeV, corresponding to a total integrated luminosity of 5.7 pb-1. An excess of four-jet events is observed with respect to the standard model predictions. In addition, these events exhibit an enhancement in the sum of the two di-jet masses around 105. The properties of these events are studied and compared to the expectations from standard processes and to pair production hypotheses.
