Abstract

Four-fermion events have been selected in a data sample of 5.8 pb(-1) collected with the ALEPH detector at centre-of-mass energies of 130 and 136 GeV. The final states l(+)l(-) q(q)over bar, l(+)l(-)l(+)l(-), nu(nu)over bar q(q)over bar, and nu(nu)over bar l(+)l(-) have been examined Five events are observed in the data, in agreement with the Standard Model predictions of 6.67 +/- 0.38 events from four-fermion processes and 0.14 + (-0.05)(+0.19) from background processes.
