Abstract

The analysis of the newest data on the leptonic $Z$ -decays and $m_{W}$ appears to reveal the first manifestations of electroweak radiative corrections. In fact, these data differ, at the level of $2 σ$ , from their electroweak Born values, while they agree, to within $1 σ$ , with the theoretical values which take the electroweak radiative corrections into account. Previous data were within $1 σ$ in agreement with both sets of values.
