抄録

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.
