Measurement of the Running of the Electromagnetic Coupling at LEP
The study of low-angle and large-angle Bhabha scattering at LEP gives access to the running of the electromagnetic coupling. Two recent measurements of the OPAL and L3 collaborations probe the running of alpha in the regions 1.8GeV^2<-Q^2<6.1GeV^2 and 1800GeV^2 <-Q^2 <21600GeV^2, respect...
