Abstract

The differential cross-sections for e₊e^- → e⁺e^-, e⁺e^- → μ⁺μ^- and e⁺e^- → τ⁺τ^-, and the total cross-section for e⁺e^- → qq̄ at centre-of-mass energies of 130-140 GeV were studied using about 5 pb^-1 of data collected with the OPAL detector at LEP in October and November 1995. The results are in agreement with the Standard Model predictions. Four-fermion contact interaction models were fitted to the data and lower limits were obtained on the energy scale A at the 95% confidence level.
