Abstract

A search for ℓ⁺ℓ^- qq̄ (ℓ = e, μ) four-fermion final states in high multiplicity events has been performed at √s ≈ mz and above the Z peak at √s = 130 GeV and √s = 136 GeV. The data taken with OPAL correspond to an integrated luminosity of 132.4 pb^-1 and 5.3 pb^-1 at √s ≈ mz and √s = 130-136 GeV, respectively. While at the Z resonance the data are in good agreement with the Standard Model predictions, we find more events than expected at √s - 130-136 GeV, especially in the μ⁺μ^- qq̄ channel, where 5 events remain after all cuts, with only 0.6 predicted by the Monte Carlo simulation. For all center-of-mass energies the observed shapes of the differential distributions are consistent with the predictions.

N2 - A search for ℓ+ℓ- qq̄ (ℓ = e, μ) four-fermion final states in high multiplicity events has been performed at √s ≈ mz and above the Z peak at √s = 130 GeV and √s = 136 GeV. The data taken with OPAL correspond to an integrated luminosity of 132.4 pb-1 and 5.3 pb-1 at √s ≈ mz and √s = 130-136 GeV, respectively. While at the Z resonance the data are in good agreement with the Standard Model predictions, we find more events than expected at √s - 130-136 GeV, especially in the μ+μ- qq̄ channel, where 5 events remain after all cuts, with only 0.6 predicted by the Monte Carlo simulation. For all center-of-mass energies the observed shapes of the differential distributions are consistent with the predictions.
