Small-angle Bhabha scattering data recorded at the Z resonance and large-angle Bhabha scattering data recorded at root s = 189 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 alpha(-1)(- 2.1 GeV(2)) -alpha(-1)(-6.25 GeV(2)) = 0.78 +/- 0.26 alpha(-1)(- 12.25 GeV(2)) -alpha-(1)(- 3434 GeV(2)) = 3.80 +/- 1.29, in agreement with theoretical predictions.

Abstract

Small-angle Bhabha scattering data recorded at the Z resonance and large-angle Bhabha scattering data recorded at root s = 189 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 alpha(-1)(- 2.1 GeV(2)) -alpha(-1)(-6.25 GeV(2)) = 0.78 +/- 0.26 alpha(-1)(- 12.25 GeV(2)) -alpha-(1)(- 3434 GeV(2)) = 3.80 +/- 1.29, in agreement with theoretical predictions.
