Small-angle Bhabha scattering data recorded at the Z resonance and large-angle Bhabha scattering data recorded at 's s189 GeV by the L3 detector at LEP are used to measure the running of the effective fine-structure constant for spacelike momentum transfers. The results are α−1(−2.1GeV2)−α−1(−6.25GeV2)=0.78±0.26 α−1(−12.25GeV2)−α−1(−3434GeV2)=3.80±1.29, in agreement with theoretical predictions.Facultad de Ciencias Exacta
